Ok, there are 2 more main characters and a bunch of secondary ones. I would start writing about Drade, but his story isn't fully developed yet. I guess I'll start on Kalit, then, even though he doesn't have a past right now(I'm workin on it...)

Kalitalis, aka Kalit or Shade, is a member of the both infamous and famous Eclipse Organization. The Eclipse Organization is led by one man, who accepts payment in return for sending his teams of trained assassins to accomplish any “objective” that the employer demands. The assassins, in turn, receive free training in battle, food, and shelter. The Eclipse Organization is widely known for its variability: depending on who hires it, it could be either very good or very destructive.
The highest ranking assassin team is team V-15, consisting of codenames Shade, Peregrine, and Vertigo. It is widely known that when these three are on the job, their victim has almost no chance of survival. They are feared throughout the world, but no one knows what they look like except those in the Eclipse Organization- any who have seen them are promptly killed.
Kalit himself is quiet and speaks little, and is focused and calm at all times, even in the midst of a dangerous mission. He refuses to reveal his past and claims that it has no importance; all that matters is the here and now. Kalit has become close friends with the other two members of V-15, and would protect them with his life if the need arose, as they would do for him. He always wears black and, during battle, a flowing, dark red scarf that covers his mouth.

Fighting Style: ? (I dunno right now)
Elemental affinities: Wind, Darkness, Water (Actually ice for Kalit, but it’s the same element)

Peregrine is a dangerous fighter who knows nothing but what the Eclipse Organization has taught her. In fact, she doesn't at all remember her life before joining Eclipse... To most people she seems cold and emotionless, but to the other members of the team she is a trustworthy friend. For the most part, Peregrine speaks only to her two friends: Shade and Vertigo.

Eclipse Organization Record 121067
Codename: Vertigo
True name: -
Preferred weapon: ? (moves at extremely high speeds, rendering weapon and fighting style invisible)
Hair color: silver (?)(wears hood)
Eye color: unknown (wears blindfold at all times)
Gender: M
Height: 6’ 4”
Assigned team: V-15
Years of experience: classified
Age: classified
Background: classified

Vertigo rarely speaks, and never reveals his face or even his hands to anyone. He constanty wears a cloak that covers his entire body. He also wears a blindfold, but it does not seem to hinder him in battle. Since he only speaks extremely rarely, Vertigo seems to have no personality.

Heheheh... if you look closely, there are quite a few hints to Peregrine and Vertigo's secret pasts in those stat list things. I'll give a hint to one of the hints: the Record numbers are assigned to assassins in the order that they join the Eclipse Organization.
