Sonja: Accuracy over brute force, Sonja and sniper rifles go hand in hand. A very calm and tactical thinker, she will be able to read the ebb and flow of the warp more easily than the others, protecting her shots from much of the warp fuckery. While she does inflict enormous damage, she is very vulnerable while shooting and has no crowd control abilities.
Elizabeth: Fire! Fire everywhere! this psychotic sister prefers her enemies blackened. Bombastic and obsessed, she will cover everything in promethium, including allies who get too close. Tactical placement can prevent this, but her twitchy personality can lead her to misinterpret a threat, or charge into a trap. Annihilates crowds completely and utterly.
Twins: both must be taken. The twins are efficient and deadly, they work off each other with skill, speed, and precision unmatched by any single entity and are quite skilled with their jump packs. The injury or death of one will most likely make the other useless.
Rodwen: As much as she hates humans, she hates chaos ten-fold. Her psykic support could turn the tide of battle in your favor. She holds no loyalty to you, but will save you if she must. This, however, does not extend to your allies.
Filigree: quick and cunning her speed will surpass a lot of what you fight. Her daemonic nature will give you an edge and may help with navigation. Her lack of armor may get her killed, and "Quizzy" would never forgive you for that. You must suppress your divine aura or risk burning her.
Pain Strider: Knows the warp better than Filigree. Her daemonic nature and knowledge is guaranteed to help with navigation. She is poor in combat and can't use weapons, however, it is very hard to kill her. You must suppress your divine aura or risk burning her.
