Simple:

Don't be a jerk.

Try to use proper spelling and grammar, if possible.

Use common sense.

No meta-gaming, nor god-modding.

Name: Runia Venthrym (VEN-thrim)
Age: 21
Gender: Female
Personality: Runia is a quiet girl, preferring the company of nature to that of people. She is mostly pacifistic and extremely caring, but if something angers her enough, then she will snap, and when she snaps, she can be terrifying, as well as outright dangerous. Though she isn’t very strong, she does know how to use a dagger or two, though nobody quite knows why. A word often used to describe her by those who have seen her, but not too closely, is demure. However, she knows a good deal of skills involving hunting, survival, etc. etc. etc, since when she’s not working, she’s probably in the woods.
Appearance:

Preferred Weapon: A pair of slim stilettos with ivory handles and white-dyed blades. Exactly how they were dyed white, nobody knows, and nobody feels comfortable enough around her to ask. The only thing they’ve ever heard from Runia about them is that they’ve been passed down through her family for a long, long time.
Profession (If applicable): Runia works as a washerwoman in the nearest village.
Etc.: Although she indeed has a preferred set of stilettos, her preferred tactic is NOT using them and instead being diplomatic and talking things out, not simply fighting. As stated before, she is mostly a pacifist.

Name: Rubix

Age: 27

Gender: Male

Personality: Rubix - the perpetually disgruntled. He isn't a particularly happy fellow, and seems to hold a great deal of contempt for humanity because of its innate "laziness." This is likely due to the fact that his mother left his father immediately after giving birth as she, "didn't feel like dealing with a child," and his father named him simply off of the fact that he was solving an ancient puzzle cube at the time. Otherwise, Rubix is cunning and sharp, never missing a single detail, and always prepared with a comeback.

Appearance (Picture if possible):
On his left shoulder, he has a tattoo of square made of nine smaller, multicolored squares forming a Rubik's Cube pattern. He's kind of obsessed with the motif.

Preferred weapon: Two slate black rods of unknown origin, each bearing a square comprised of nine smaller silver squares towards the top to form brands. Otherwise, they're just two beating sticks with no shape other than being long cylinders.

Profession (If applicable): Professional vandal. Is paid by others to destroy another's property, reputation, or life.

Etc. Would never be caught dead without a pair of dice, a deck of cards, and guess what... a Rubik's Cube.

Etc.:

Name: Adriene
Age: 25
Gender: Female
Personality: Not many people know Adriene well enough to know her personality. The few that do would find her difficult to describe. At first she seems somewhat psychotic but she is far too stable to be labeled as such, most of the time. She is a genius and often spouts random facts. If anyone could get close enough they would find her to have a macabre sense of humor but an artists soul.
Appearance:
Preferred weapon: Pistol but she is skilled in almost every kind of combat imaginable.
Profession: Bounty hunter
Etc.: She is a gifted dancer
