Darshee the dark elf
A dark elf specializing in earth-related magic. Like most dark elves, Darshee Torydark lived in an underground city, studying magic with the sisters of her order. However, her sanctuary was attacked by the Naegeiros, a clan of evil elves who wanted to steal the sacred magic texts from her order. Her companions were killed, and Darshee was kidnapped by the Naegeiros, who planned to use her to extract information from the ancient magic texts. She was freed from her captors by the group of mercenaries known as War Ensemble, after which she decided to join them in gratitude and to avenge the death of her sisters. Now she's a dark elf working alongside humans.
