Tairax appeared on the island of Terros Nui (BZPRPG) along with the other Wartooth members, serving Ma-Mori, the Makuta of War. In an effort to plunge the island into chaos, Tairax sent an ultimatum for the citizens to either assassinate Alzuth or have an innocent civilian killed each night. Several Terros Nuiians rose up to the challenge, and Tairax's first mission proved to be a success.
