See: Lucy, Mercs for Hire
Lucy is a fair Human girl. She grew up in a poor but well faring little family near the coast of Crescent Bay. She was close friends with Yunan when they were younger. When she was 13, she was playing with Yunan, when suddenly a volley of arrows besieged their village, one hitting her in her back. Yunan got scared and took off, assuming her dead, but she wasn't.
After that Lucy left her home, and started studying the arcane arts. Ten some years later she has become quiet a strong sorcerer, just when Yunan needed it.
