The able lieutenant of Manshoon for years, Sememmon served for years as the Lord of Darkhold. He rose to that rank by being unfailingly polite, competent, and obedient to the letter of orders given by Manshoon, Fzoul Chembryl, and various Zhentarim beholders. Beneath his quiet politeness, he's cunning and calculating, capable of holding grudges (but not allowing himself to be driven by them) for years. He always has a ready escape from any dangerous situation and does not hesitate to use it.
Sememmon is a capable wizard, a former apprentice to Manshoon, and a survivor, swift to ruthlessly eliminate rivals and elude blame. He foiled a number of Fzoul's bids to seize command of the Zhentarim and thereby earned the priest's undying enmity - but he also protected and husbanded the power of the Zhentarim through the wildest excesses of both Manshoon and Fzoul, calmly "picking up the pieces" on many occasions. In the process, he became a master of diplomacy and foresight, a good commander of troops, and a master strategist who always has several fall-back plans (and hidden magic items) at the ready.
Sememmon is mild-mannered, observant, patient, and keenly intelligent. Ruthless and tightly controlled, he's no egomaniac or lover of tyranny, and detests unnecessary violence and cruelty as wasteful. He loves and is loved by his cohort Ashemmi (LE female moon elf Wiz11). For years he remained loyal to the Black Net work-indeed, in the opinion of observant Zhentarim, he was the Black Network, having kept everything running while his superiors raved, pursued mad schemes, and fought each other. The radical increase in Fzoul's power signaled the end of the priest's tolerance with anyone who opposes him, and Sememmon and Ashemmi fled Darkhold before Fzoul could act against them.
Sememmon is a black-haired man of handsome appearance, middling years, and excellent health, who wears conservative but well-made robes. He uses magical disguises when traveling. He seems calm even in the heat of battle and while facing great danger.
