Yamasoth is a qlippoth lord, yet many scholars persist with the notion that Yamasoth is actually a nascent demon lord, maybe the only qlippoth currently at that rank in the Abyssal hierarchy. This is wrong, and Yamasoth himself is angry at this misrepresentation.
Yamasoth rules over the Kingdom of New Flesh, a large part of the Abyssal realm of Sekatar-Seraktis. Thirteen other powerful demons war over the control of this realm but seem to leave Yamasoth to his experiments.
The Kingdom of New Flesh is home to hundreds of thousands of his test subjects, which Yamasoth collected from various planets and transformed into twisted monsters via fleshwarping. None remembers their name or personality. Gongorinans, Yamasoth's favoured qlippoth, serve as functionaries and defend the Kingdom of New Flesh.
More evidence of a qlippoth nature is in Yamasoth's bizarre appearance: a basis of an octopus or large squid is perverted by extra tentacles and eyes. A large mouth contains an extra eye in the throat, which only opens in combat to release a gaze attack turning victims wild and monstrous. A common factor in his physical make up is the ability to cause pain: teeth, stinging tongues, and the termination of every tentacle with each one boasting a different way of inflicting pain.
Yamasoth once inhabited the realm of Gongorina, in the deepest parts of Sekamina in the Darklands, directly below the Varisian Gulf. This was his laboratory on Golarion, where he experimented on troglodytes from Kuvhoshik, driders from Umberweb, and other creatures from the surface. From Gongorina, Yamasoth had tunnels that ran to the Thassilonian city of Xin-Bakrakhan at Hollow Mountain and to Sekatar-Seraktis. This latter tunnel still exists, though Yamasoth no longer travels to Gongorina. Alaznist, the final runelord of wrath, was allied to Yamasoth when the qlippoth lord lived in Gongorina: she provided him with test subjects and he bolstered her armies with his creations. It is believed that if Earthfall had never happened, Yamasoth would have launched a massive qlippoth invasion of Golarion, but the devastation wrought by Earthfall forced him to return to the Abyss.
Yamasoth despises almost all other deities. He both disdains and grudgingly respects Lamashtu, both for her creation of various monsters and her status as the strongest demon lord. Followers of Lamashtu and Yamasoth might cooperate when conducting experiments on unwilling subjects, but almost always turn on each other.
Yamasoth abhors Haagenti: both claim to be the original inventor of fleshwarping and considers the other a plagiariser. Their worshippers rarely clash, since Yamasoth's cult is concentrated on the surface of Golarion, while Haagenti's drow followers usually live in the Darklands.
