House Se'Sehen

House Se'Sehen was a tribe of snake-headed yuan-ti known for their ability to spit venom. Members of this tribe were called Se'Sehren.

Base of Operations
House Se'Sehen was the largest and most powerful house within the Black Jungles as of 1372 DR, having seized the former lands of House Hss'tafi when they disappeared in the. This also included both the Pit of Vipers and Ss'inthee'ssaree.

Relationships
The Se'Sehen aided Sseth during the deity's initial rise to power when establishing the empire of Serpentes and were awarded the lands of the Tashalar basin for their efforts. The Se'Sehen counted the members of Houses Extaminos and Sauringar as close allies.

Members of this tribe were frequently at odds with the Coiled Cabal as both groups thought they were the rightful crafters of yuan-ti dominance in Faerûn.

The Se'Sehen clashed often with House Eselemas and House Jennestas, given their land claims within the Black Jungle.

Activities
The Se'Sehen experimented extensively on creatures found within the Black Jungle. They created the ti-khana, which served their tribe loyally.

History
The Se'Sehen were forced to withdraw from Tashalar in the just ten years after Sseth's disappearance. This ushered in centuries of somnolence for the tribe. Sseth's reappearance during the Time of Troubles in 1358 DR reinvigorated the tribe, prompting them to forge an alliance with the Rundeen slave and trade consortium of Tashalar. The Se'Sehen exchanged exotic poisons and spices for slaves and transportation of their agents to the ports of the north, scattering their eyes across Faerûn. Among these spies were members of House Extaminos.

House Extaminos' split from House Se'Sehen occurred when a pair of strong claimants for leadership of House Se'Sehen rose to power. Instead of crippling the house with pointless civil war, the two decided to split and allow any Se'Sehen to choose which side they would follow. The claimant's group with the greater numbers would remain as House Se'Sehen, while the other would form a new house and lead his followers to a new location.
