Vaeril

A fallen druid who van take the life force from the trees and make it his own to fuel his magic. Rather than sharing energy with the forest, he saps it.
Because of his sinister powers, the elves have banished him from their territory and he is now living in exile, alone, hiding in the woods.
Those who have met him tell that he has the eyes of a sad man, one with more regrets than they're sure de'd care to share.
He's hunted by Kusho, a talented assassin.
