Manshoon

Manshoon was the founder of the Zhentarim, also known as the Black Network, until he was "slain" by Fzoul Chembryl, his ally, and Lord Orgauth in 1370 DR. However, it transpired that Manshoon had created a dozen or more clones that the murderous duo then found themselves facing. There are currently three clones in existence.

Personality
For years Manshoon was the lord of Zhentil Keep and leader of the Zhentarim. Completely fits the archetype of the sly-tongued, sinister and decadent master spellcaster, Manshoon ruthlessly crushed revolts within his own ranks of the Black Network, easily slaughtered his rivals and weeded the weak out of the ranks of the young and ambitions by sending upstarts on nigh-impossible suicide missions. Hated and mistrusted by Fzoul, Manshoon manipulated him much as he did all others - remaining arrogant, untouchable in his power and faintly amused by it all.

History
Manshoon founded the Zhentarim through guile, murder, intrigue and magical might. He has created a grand cabal out of the likes of the wizards named the Black Cloaks, beholders, wealthy Moonsea merchant and servants of evil temples - most notably, that of Bane.

In 1370 DR, Manshoon was "slain" by Fzoul and Lord Orgauth, who then found themselves facing around a dozen clones that the wizard had created. Each of the clones was convinced that he was the real Manshoon and was inexplicably compelled to slay his rival clones. Most of these perished in the ensuing battles. The caches of magical items formerly hidden by Manshoon were scattered throughout the Realms.

Three clones, who mastered this killing compulsion by means of spells and devices, survive with the one that returned to the Zhentarim appearing to be 'the' Manshoon. Used to ruling and manipulating from behind the scenes and relived of responsibility of administering to the Black Network, he seems to have learned a lesson in caution and patience. He has since redoubled his arcane research, seeking ways to transfer his consciousness from one clone to another at will.

The clones
One of the three remaining clones has now returned to the Zhentarim, conceding leadership to Fzoul and entering in to some sort of secret accommodation with him. He serves as a member-at-large, a free agent with the power and authority to direct Zhentarim assets as he sees fit. The second clone is rumored to have assumed a position of power among the thieves of Westgate, calling himself Orbakh. The third has taken refuge in Undermountain with Halaster.
