Filia ul Copt

Filia was a priestess of the first holy order under Flarelord. She obeyed the orders of the elders at her temple, and as a result, she had a rather naïve and biased view of the world. Until she began traveling with Lina Inverse's party, Filia did not know of the barbaric acts of violence her race took part in around the time of the Kōma War. Near the end of Slayers Try, she gave up her priestess position, and by the time the whole Dark Star Dugradigdu ordeal was over, she found that she was the last remaining follower of Flarelord, the rest of her clan having been destroyed.
