City of Splendors: Waterdeep
Sememmon was mild mannered, observant, patient, and keenly intelligent. He was also cunning and calculating, but he controls himself. Sememmon was both ruthless and implacable.
Sememmon knew which way the winds were blowing so he and his consort went rogue from the Zhentarim. Sememmon knew that the enemies of his enemy, (Fzoul Chembryl), are his friends. He planned to make himself available to the forces of good. His goal was to make himself indispensable to the countries, nations, and people he once opposed.
Sememmon often disguised himself and asked groups of adventurers to perform tasks on his behalf, and he always kept his word in this regard, never abandoning those working for him.
