Here's another character I've been sitting on for a while.

Ludmila was born into war, fighting for an army she was bred to fight for.
Young and foolish she followed orders and committed many atrocities in the name of a benefactor she had never even seen.
As the years passed and the fighting continued she began to question it, finding answers to the questions no one around her bothered to ask.
Learning that the aide she had been fighting for were the aggressors and evil of the war she quickly turned sides, taking her troupe with her as they fought against all that she once defended.
Though not through her efforts alone, the war was won and she was free to roam the world as she saw fit.
She was hated and feared by the masses who only knew her and her kind for the evils they had committed and saught to make amends.

Now she travels the land, aiding young adventurers who seek to make the world a better place. Her time with these groups had made her very protective of those she deems her friends and will always make sure those she cares about are safe, fed, and happy.
