Galin

Galin was a slim, nervous looking Elf with a dark secret. He the former warder turned leader of the Elven village of Gorgan, in the Shirani Forest. 
Rising to leadership during a terrible dragon raid on Gorgan, he is described by villagers as suffering under the weight of leadership, and the deaths of over 100 Elves, including his own wife, Sonia.
When Nerovain and Parizad  began destroying villages and killing or abducting Elves to the last one, Gorgan was to some degree spared. It turns out that Galin made a deal with Parizad during the Gorgan raid to spare his village in exchange for providing information on locations and tactics of other villages. He would secretly meet with Nerovain and Parizad outside the village on a regular basis, using his raven companion to help communicate.
Outed by Rocks, Rocks, and More Rocks, Galin was eventually stripped and exiled by the Druid Calantha, after his transgressions against the Elven kingdom were uncovered.
