Keep in my mind that these ideas are all works in progress. Developing them before hand is probably best before actually starting them.
Still a name in progress.
This story follow two families, very powerful both physically, and in terms of actually having power, they can cause a country to fall into chaos or of they so want to suffer destruction. Both families are immortal, and have unique powers for their own use. They have been in conflict for centuries, sometimes one family suffers more significant loses than the others, sometimes they are in stalemate. If a member chooses to leave their family for a quiet life, they must have their memories wiped and the use of their powers sealed away.
Of course, that depends on if the family member has fallen in love with another. Two members from the opposing families have developed feelings for each other. They have had enough of this war, and just want to spend their lives with each other. But of course, the families have a strict code, and they don't want any loose ends, especially if the runaways are from opposing families.
Basically Baccano! meets Darker Than Black. this one requires more developing in my opinion
A Metropolis run by and created by the world's greatest Cybernetic/enhancement Companies. Shangri La Stands as its own Nation and Country on Earth, and being the most powerful of what is left of Earth's other nations. the City builds itself upon one motto "Personal Enhancement builds to a brighter future". This means civilians can under go any kind of Enhancement from cybernetic to newly created Neural and Internal Nanotech Procedures( increases physical and mental Performance, to what degree varies.).
Law Enforcement is a collaborative thing in Shangri La. While the average Officer and law enforcer carry on their duties in investigations and petty crimes, powerful androids called Sentries have been created for the sole purpose of hunting down wanted criminals and stopping terrorist acts and much more severe crimes. Sentries are the Enforcers created by "The Prophets" Leaders of Shangri La that act as father and teacher to the city. They also have their "specialist" division called "The Collectors", cybernetic enhanced agents that carry out more morally ambiguous tasks.
The most notable and biggest crime to date is whats known as "Illegal Enhancement crimes", this is the act of installing and enhancing one's self illegally, with the use of stolen and black market enhancements, which include weapons. In a city such as Shangri La, this is by far the most profitable crime any gang or criminal organization would want to get their hands in. Black Market Limbs are retrieved, and Black Market Surgeons, are always around for such crimes. Another group has quickly rose to be a counter to The Collectors, and that is Broker Agents, mercenary like Agents that are hired for certain jobs. Escorting, protection, assassination, anything that the Crime organizations or Gangs can afford.
I haven't decide on a plot specific for this yet, but I'm willing to work one out though.
Demon Based/Supernatural RP Idea
When demons enter the human world, they have a limited time to possess someone, usually within a week they must find a suitable host, a human to become their vessal so they can discover the human world for themselves. but as humans started to develop, and their understanding of the world around them grew, some discovered secrets in the arcane arts, becoming what people call witches, wizards or "Enchanters". They soon created away to channel the demon's need and want to discover this world, by creating "Contracts", powerful binding spells used to anchor the demon to a host, and giving the host increased powers and abiltiies
Contracts bind a demon to a human host, but at first it took all of the hosts power to summon the demon out of their body. Eventually this relationship between host and demon grew, and their power together would increase, which lead to the discovery of the demon changing shape, more precisely into a weapon, or to give their host a powerful transformation, often seen as armor.
After awhile, demons soon promised humans that they would give them all their powers, along as they don't bind them to a contract, however, these demons would trick the host, and take control of the body, leaving the host a damaged wreck of insanity for the demon to full take over.
This lead to the formation of the "Third Sons", a group of enchanters and binders(those with a contract), to put a stop to these demons, and send them back to the Underworld, but they soon discovered a threat more dangerous than mindless demons looking for unbinded hosts, the "Devil Beast", a creature that consists up to a large amount of demons in a single body, in which the demon's become a legion, twisting and changing the human host into a monster without reason, replaced by animalistic urges and instincts, either looking very similiar to humans, or becoming grotesque monsters.
As of now, The Third Sons have spread all over the world, to keep demons from flooding in and causing mayhem and destruction, but one of the best binders, has relinquished his owns contracts(the only binder to have three demons), and become an enemy, looking to throw the world iinto darkness. a team has been assembled to stop him
This idea is a Dystopian Sci Fi Idea.
So a Scientist has been studying various new forms of A.I. essentially finding a way for a certain A.I. to develop on its own from a dog level intelligence, into human intelligence, and possibly further. His first prototype is that of a companion Drone called "Z3" a present for his daughter. The drone and the young girl develop a bond with each other, the Drone's intelligence ever increasing, even developing emotions of brotherly love towards the young girl, to the amazement of it's creator. While the Drone and the girl bond and become almost like brother and sister, the Scientist has tried to keep his experiment a secret, believing that his idea and project could become something terrifyingly evil in the wrong hands. That's when the "Men in Black Suits" appear, working for a not so big, but really powerful Cybernetics company called "MirageTec" as they discovered the Scientists pet project. This does not end well as you may have thought by now. They kill him, and take his legacy, all of his notes, his other experiments. Z3 tries to stop them but is essentially disabled, the young girl crying as she saw her only friend being treated in such a way.
Years have gone by, the world has been ravaged by a war, leaving most of the land a desolate waste. The home of the scientist now houses a strange, and Psychotic Cybernetic Expert, who finds the Drone and pretty much takes him apart and places him in a stolen, and very powerful Cyborg Body created by MirageTec. The initial reactivation causes Z3 to go on a rampage, killing and ripping apart the various droids and cyborgs and even the scientist himself. Confused at his new body, Z3 starts his journey by looking for the scientist's daughter. He eventually finds a resistance group, who believe that MirageTec's Paradise "SCI City" should be open to everyone, instead of only those that can afford the Cybernetic Enhancements. Z3 learns of the Resistance Leader, A young woman who looks remarkably like the young girl, even though the leader is older in age.
That's the basic idea of this one, I'm willing to change a few aspects if you feel the need it could with some refinement. I already have an idea of a Villain, well a group of Villains anyway.
After the War known as the "Great Arcane War" a truly devastating period of which Science and Magic were used to battle one another, the world changed, landscapes moved, cities became desolate, until a weapon was used which completely wiped the memory of humans clean, they only remembered this terrible war and the sudden mysterious end to it. They vowed to recreate this world and not relive that experience.
It was then humans learned to combine both science, and magic to create armaments known as " Tri-Arms" powerful tools used to channel magic through scientific means, ranging from simple wrenches, to highly advance peices of machinery. it was then villages were build, becoming towns, and then cities, with others growing around these large cities.
Pandora, a huge walled city was the largest, and most advanced of them all, created the unthinkable, a biological, powerful Tri Arm that was a human, the first Victus Telum, "Living Weapon". Living weapons are powerful human beings who use "Tri Arts"(Magic), naturally, referring to it as magic. These newly created lifeforms were shunned by humans, fearing them as "powerful weapons with deadly capabilities" eventually Living Weapons became outcasts, forced to leave the city, with only a select few that were under the control of "The Guard" a powerful Military and Research company, that wanted to use a select as weapons.
If anyone is interested and want to develop the following Ideas above then of course reply to this thread, VM or PM me which one interests you and we can see from there .
Also, I'll update with new ideas when I can.
