Manshoon

Founder of the Black Network - the Zhentarim - 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 'Manshoons' in existence.

Personality
For years Manshoon was a lord of Zhentil Keep and leader of the Zhentarim. He fits the archetype of the sly-tongued, sinister and decadent evil master spellcaster, ruthlessly crushing revolts in the ranks of the Black Network, slaughtering his rivels and weeding the ranks of the young and ambitions by sending upstarts on impossible 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, forming through guile, murder, intrigue and magical might created a cabal of like-minded wizards named the Black Cloaks, beholders, wealthy Moonsea merchant and servants of evil temples - notably Bane's.

In 1370 DR he was 'slain' by Fzoul and Lord Orgauth, who then found themselves facing clones that Manshoon 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 and the caches of magical items formerly hidden by Manshoon were scattered.

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 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, conceeding leadership to Fzoul and entering in to some sort of secret accomodation 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 rumoured to have assumed a position of power among the thieves of Westgate, calling himself Orbakh.

The third has taken refuge in the Undermountain with Halaster.
