Event on Colossal Cavern

Murdock the Centaur canters out to meet you. He explains that despite their association with the warlocks, centaurs are a gentle folk and not inclined to battle. Their service to the warlocks is the result of a debt long ago repaid. Yet the warlocks will not let the centaurs go free, relying on them for missile attacks in mixed forces. However, he says if you swear to overthrow Wyrminthal, they will rise up and fight at your side.
