The party freed Tullis from a spirit mine, which had been deployed by exterminators attempting to clear a mimic infestation from the Great Library of Boccob in Panthium. After being released from his extra-dimensional prison, Tullis offered the party a stake in his new trading venture, which deals in the trade of exotic material -animal skins, magic reagents, etc. The party agreed and each invested a certain portion of their income in the Four Winds Trading Coster.
