Bian Valar
Bian Valar is a model hired by Evelyn's unofficial combat arena fan club to pose as her for their banner artwork. She grew up on Skaloth and idolises Evelyn.
Bian's mana was inhibited by a curse or corruption of some kind. Evelyn donates some of her mana to Bian, resulting in the latter's mana being unblocked and becoming very strong.
