Tailas is a resident of the Werewolf Village, which is located on the southern half of the Isle of Balduran. He can be found in the Chieftain's House along with Kaishas Gan. He is against giving Gorion's Ward the "gift" so that he might "belong" with them. He has turned the villagers against Gorion's Ward and will attack after you complete the task of killing Karoug and finish speaking with Kaishas Gan.

I sure we could have resolved things, but other members of the village would not have it. I must fight my way through them now and escape as best I can.

—  Gorion's Ward
