Talion was a being that inhabited the body of an elderly elf.
This elf lead a party of adventurers to White Rock Ridge in the search of a White Stallion. There, in the temple, he revealed himself to be the White Stallion and a druid with a crown of antlers. He asked the party to defend the temple from the forces of evil or darkness would fall over the land. During the battle Talion was sapped of most of his strength because of a green necromantic crystal. After the battle the being left the body of the elf who fell lifeless to the ground.
