Got something for ya: A solo spirit. Anyone interested in trying to make a pact with him can try to find him once the IC is up.
Appearance: 
His "true" appearance is more akin to a black gaseous shadow with no real discernible features. The image above is merely something he may wear rather than what his true appearance would be.
Name: The Harvester (Harvey to his friends).
Age: 500 years, give or take. He doesn't keep track.
Backstory: The spirit known as The Harvester did not truly get his name until much later into his life, by his first master. His existence began in a cold and desolate place in the Varisie Empire. Specifically, in one of their graveyards. He simply found himself, a mostly fleshless entity, amongst the respected dead of the north. The Spirit was not sure what he was doing there, only that it felt drawn to the dead. Their emptiness made him want to fill the void with his essence, his very being. But he was not a spirit of death, but a spirit of life. He wanted to bring life to these corpses, but fought the urge. He did not know what he was doing here, so he set out to discover what he was.
Initially, the spirit was nothing more than a vaguely humanoid black wisp. He lacked the flesh and blood most humans have, and indeed, what most spirits had. He had the essence of life but not the body. He would not disturb the dead however. He didn't know why, but he simply felt that he should not. He rationed that it would be too difficult, but he also thought it wouldn't be right to defile their graves. Of course, that sense of honor didn't stop him from killing the first person he saw and possessing his corpse. At the time he thought nothing of it; that person had a life, so he would simply take his body. He was unaware of how humans lived and died, and he wouldn't learn until much later after much catastrophe.
In the mean time, the spirit took possession of the new body and borrowed it's identity. The first order of business: Figuring out what it was. So the spirit took it's body into the human lands. The spirit went into the human lands and began to ask questions; to know what spirits are, and where he was, and who he is. For the longest time many humans would ignore him. "Strange" they would call him. "Insane" even. He knew these words but didn't think they applied to him. He was wanted to learn, is all. It wasn't until the spirit was confronted by this strange man who the spirit recognized as a religious leader of some sort. Priests, they call them. He offered to take the spirit in and give him shelter. The spirit also asked for knowledge, which the priest was kind enough to oblige.
The priest taught the spirit of what spirits were; how they embodied natural elements and grant powers to humans. But he also preached the dangers of spirits and how they must be controlled, and generally made things very unpleasant for the spirit listening. He made his excuses and left the chapel as soon as he could. Once he was gone, the spirit started to wonder what it would do with itself now. It was a spirit with some sort of magical power. He knew he could control life, but what did that mean? How does one go about doing that? He had no teachers, and instincts failed to teach him. So he would go and learn. The spirit began to practice, honing his powers and trying to understand it... For a couple of days. Than he got bored.
What followed would be the relatively mundane life of the spirit. As a spirit he had no need to eat, but his body did. So he had to get food. But to get food, he had to give things to people. Money, they call it. And to get money he would need to work. So the spirit went to look for work. He had many jobs; sometimes he cooked food, other times he made shirts. Once he was told to kill people and given money for that. When he was told to do these things, he did them fairly well, after a couple years of practice. He learned how to make delicious food, or how to weaver pretty embroidery, or kill a man with whatever was on hand, and even began to fight against other spirits. That was when he first got his name.
He wasn't sure how they figured out he was a spirit. Maybe they just thought he was too strange. Either way, some people from a holy place killed his body, but sealed his essence. They told him that he had to work for them, or they would kill him. He didn't know if they could, but he didn't know a lot about himself. He did as he was told and worked for an "Inquisitor" by the name of Cypress. Cypress was a stern, but secretly kind man. He would always yell and punish the spirit when he didn't do something, but he also gave the spirit a name and purpose. He became The Harvester, he who reaps the bounty of life. He was the one who taught the spirit, not The Harvester, who he was and what he could do.
Cypress did not just summon The Harvester when it was time to fight. Cypress, being a kind man, wanted to know more about The Harvester. What he knew, what he could do, what he could learn. He helped The Harvester control his power of "life". At first it was just possessing things; boxes, jars, the occasional door. But than began to discover more applications. The Harvester could make things move even when they are normally motionless; he could life things without touching them. Again, it started with just boxes, jars, and doors, move them around, throwing them, opening them. But than they started to try more complicated things. Machines. Bodies. And small things, like people's shoes. Or bullets. While they're flying through the air. Cypress made The Harvester learn how to use his powers, discovering more of what he could do ever year. The Harvester learned how to see the life in everything, so he could tell when someone or something was dead so he could possess it, or simply just finding people in general. He could tell the difference between spirits and people as well, and at some point was able to tell even individual people and spirits apart. The ability Cypress liked the most however was how The Harvester could share his life with Cypress.
Cypress spent forty years training The Harvester when they weren't out on missions. Cypress was considered one of the best Inquisitors, but he was also human. He grew old, weak, and he would start dying. The Harvester didn't like that. He was a Spirit of Life; he wanted to make sure that his friend would live. So that's what the Harvester did. For befriending him, The Harvester used his power to link his life with Cypress. So long as The Harvester lived, so would Cypress. But it was too late for him; Cypress was an old man. Though he was thankful for The Harvester's attempt to extend his life, Cypress wanted to pass on. He had lived and fought well for his homeland, and wished to die for it as well. So even after The Harvester tried to extend his life, Cypress chose death. This confused The Harvester, but he allowed it. It was the least he could do.
After Cypress's death The Harvester did not stay in the Varisie Empire forever. He left when Cypress died. The Harvester, who started calling himself Harvey, traveled around Lucenrai. For some parts of his life he'd get a new master, but they were never as nice as Cypress. Many of them were quite mean, making Harvey do things he didn't want to do or generally treated him badly. So most of the time Harvey just did what he wanted to do, which was just about anything really. Sometimes he liked fighting, so he would possess a body of a strong person and learn how to fight. Sometimes he wanted to fly airships, so he possess a body and learns how to operate aircraft. Other times he would want to build something, so he possess a body and builds things. Cypress doesn't really work with summoners anymore, and even if he did, he'll only do so if they could help him discover a new way to use his power. Most people don't know how to do that, so he doesn't really work with them.
In his most recent five years of his life, Harvey has taken up cooking again. He likes how food taste even though he now has a body that doesn't require food (It's a huge robot) and he seeks to master the art of cooking, as well as pick up any other adventures along the way.
Skills: Lots of jobs - Harvey is not an idle spirit. He has learned and is well practiced in many occupations, from tax accounting to heart surgery. Of course most of these jobs he hasn't done in a while, so he's rather rusty. Still, there's little to nothing that he hasn't done before in his vast amount of time alive. Even if it's not specifically stated, there's a good chance that Harvey has had worked in any specific field, or at least has done work in something similar long enough that he can allow muscle memory (Or what would amount to muscle memory for him) to take over. Jobs that he's especially skilled at: Cooking, Textiles, Physician, Operating Machines, and Construction..
Sharp Senses with Equal Reflex - Harvey has trained to hone his senses to a fine point, and has the required secondary training to utilize his increased senses to a reactionary level. Even though he sometimes lacks the organs for it, he has keen eyes and could hear the farts of a fly a mile away an hour before it happens (figuratively speaking), but he also has trained his senses to be able to tone that back if it proves to be more of a hassle, such as blinding himself so he won't be effected by blinding light or numbing his body's reaction to pain.
Called Shots - Harvey has a good eye for picking out weakness in a person or structure. Even if he's using a weapon like a knife or a steam rifle, Harvey can often hit where it matter's most. He has too, since he isn't really good at any weapon in particular to afford to waste time trying to poke holes into a persons' defense.
Adapted Traits - A skill more reliant on the body he inhabits; on his own this skill doesn't really matter, but when Harvey possess an object or body, he can quickly get a feel of how they would move and act at a subconscious level. This mainly helps him figure out how to best utilize the body's strengths and what it's particular weaknesses are so he doesn't struggle too long when he has to go from possessing a humanoid body to that of a cat or a bird..
Abilities:Incorporeal - Though he is a Spirit of Life, Harvey does not possess his own Physical body. Instead he appears to be a black wisp in the vague shape of a human. While this makes him immune to any physical harm, unless he posses an object he cannot affect the physical world in any meaningful way aside from his voice and what he could see. Magic can still affect him however, possibly even kill him. He wouldn't know, he doesn't try to get himself killed often enough to know what would do the job.
The Power of Life - The Harvester is a Spirit of Life, though a fairly young one who still doesn't know his full capability. His magic powers mostly revolve around "life" in it's various shapes and form, and one of the main ways to gain a pact with him is helping him discover a new way to use his magic in a way he couldn't before. Those who enter a pact with him gains the service of his power as well as his "Life Link" ability, which means that he shares his life with his Summoner; so long as he lives and remains bound, so does his summoner. Other abilities that Harvey knows now includes:
Possession: The first and most basic of Harvey's ability, which he essentially puts his own life into an object that does not have life in it. This allows him to take on a physical form which he can manipulate by making it float and move on it's own, such as making it spin. He cannot possess "Living" objects like people, at least not until he kills them. When he possess a corpse he puts his "Life" into it, essentially turn the corpse living again using his own life energy. He can even possess and bring life to rotting corpses, in which they will slowly begin to mend what remains of their body together so long as Harvey stays in their body. If they take enough damage however (Like a normally lethal amount such as decapitation), it would force Harvey to leave the body. A similar concept applies to other objects as well, though some are much more durable than others.
Telekinesis: The second power that Harvey discovered how to use. It's something akin to a remote possession, except that he can use it on other living creatures, though they could fight off the power if they are strong enough. Basically he puts his life energy into an object even if he's not making contact with it and moves it much the same why he would if he was possessing it. He has to keep track of what he's possessing and what they're doing, though he usually has a focus enough mind to telekinetically control multiple objects at once. Small objects are much easier for him to control than larger ones as they require less of his life energy to move around, including things like bullets even when they're flying in the air. If he doesn't use his keen reflects to pluck them out of the air, he can erect a sort of "barrier" where he focuses on an area where he expects something to come through. Any if anything does, he can try to control it using his Telekinesis. He can make anything that is successfully control by his telekinesis go as fast as he wants it to go.
Detect Life: The third ability that Harvey learned from his first master Cypress. It allows him to see the life in others, so he can figure out where they are and what he can possess and control telekinetically. Only effective within the first 100 yards of visual range, however he can detect life through obstacles like walls and such. He can also "Mark" things he see's with Detect Life active, even things without life, which allows him to unique identify people or objects to separate them from other things he would see. He can put on and remove as many Marks as he feels like keeping up with.
Life Link: The most important ability that Harvey offers with a pact. His forth ability allows Harvey to link his life to whomever he is in a pact with, sustaining them so long as he lives. It does not heal them so much as it does prevent the loss of their life, so if someone get's decapitated while he has a Life Link with them, they would live as a severed head until Harvey removes the link, though hopefully not before they figure out a way to put the severed head back onto the body. Harvey can remove the Life Link freely, however he can only link to one life at a time, and anything that causes him to lose his pact with his summoner also makes them lose their life link. Additionally, though Harvey isn't aware of it, should he die while he has a Life Link with someone, that person would also die with him.
Summoner Powers: Those with the fortune to create a pact with Harvey gains his Life Link, itself a rather powerful ability on it's own. Additionally they can use his Telekinesis, which he can help strengthen or manage at his summoner's digression. He can also possess his summoner's body without having to kill them, in order to move them if for some reason they can't, like if they're asleep, paralyzed, or being moved by an outside force.. It should be warned (Not that Harvey always remembers to do it) that he can instantly possess his own summoner if they don't have specific ways to counteract him. His Summoner also can see any of his Marks, but only if Harvey points the Marks out to his Summoner.
Equipment: For the given amount of "Equipment", Harvey's current body is a
robotic chassis from the Varisie Empire. Though large and bulky, this robot is actually a waste-disposal machine, and lacks any specialized weaponry aside from it's hydraulic fists. But given that it's a eight feet tall steel golem, it's only weapons are rather effective weapons. It can shoot out it's hands a fair distance and retract them back due to a steel wire. Harvey calls it the "Rocket Punch", despite the fact that it is not rocket powered. He also carries around a Scythe, partly to play up his motif as "The Harvester" but mostly because it was a gift from Cypress. It was his main weapon when he worked with him, and Harvey would use the scythe for combat if he isn't possessing anyone. The Scythe itself is ornate but non-magical. He keeps the scythe as well as his clothing (what you see in the image above) within the body of the robot.
