A force of destruction, a brutal killer, consumed by a desire for vengance. All true, yet only pieces of her fractured self. She tries to fill in the gaps with alcohol and cigarettes, throwing herself into fights without a concern for herself.
Because she has no reason to care. She has become inhuman - they made her into a monster for their war. It's time their war came to them.
Laelia is a variable, an unexpected and unpredictable addition to the world around her. She seems to revel in bloodshed and destruction, though there is an ocean of underlying anger and pain to her behavior.
This is a woman who has greeted death for a cause she thought right, only to find her soul yanked back to her body as the government she trusted used her as a science experiment. She was among other soldiers that died in their war, and they all suffered as the scientists forced them to live. Many died, their bodies deteriorating far too much to be useful. More still mutated until they were no longer human.
And then, the government abandoned the project, putting the few surviving subjects into a psuedo-statis where they were still somewhat... aware.
