"As.. Above.. So.. Below.."
One of the few remaining Demon Lords that call themselves
Obyrith, Ix'illik manifests as a house-sized soup of everchanging limbs. After crashing into the Tree of Life, Ix'illik shaped and hollowed out the structure, reducing it to a stump. Deep below the dunes of the Prison of the Gods, Ix'illik created the Fleshforge, an undulating, protoplasmic realm of hate and hunger.
The eldritch, primordial demon lord was driven primarily by the desire to reshape all living things into demonic lifeforms, and inspired Baphomet in this way, helping form the creation of The Tower of Science during the War of Ahghairon, in an attempt to defeat the Oshran Elf with new demons, 'forged in flesh'.
Though the Tree of Life gave Ix'illik his start in the Material Plane, he succame to Rot and Decay, and is sealed under the stump, now called the Tomb of Ix'illik. But the Obyrith is not bound by death, and lives on in unholy unlife; as do all who fall prey to the juices of the fleshforge.
