A centaur mercenary down on her luck

Lunara is a mercenary, through and through. Born and raised by a mercenary company she served as a scout at early age, and as captain of the light cavalry when she became older.
Her company got killed to the last man when they took a contract to hunt down a mysterious beast.
 
She was saved by the emerald enclave and served with them for a little while before splitting of to go at it alone.
