Our Material Plane
The gaunt, jaundiced looking human in the overlong raincoat was actually the spawn of York, the god of undeath and secrets, through his tampering of the Demiurge. His creation initiated the Shift and marked the next incarnation of York, who had been weakened in his battles with Lancasters and Herja 14 years earlier.
He was sent from the Tower of York to the Pale Tower in Atlas, where Mulligan trained him to infiltrate the continent. After a year, he traveled to Fife, where he was spotted by the Stormwalkers at Dignam’s funeral. Soon enough, he confronted them in Plainview Warehouse, where he sacrificed his Tiefling servant to escape.
They next met Skeith at the House of York in Saein, where he revealed his destiny as the new face of York. They followed him to Antenora and the Tower of York, where he stalled their pursuit by giving them their old enemy Saklas the Traveling Man. He tried to port from the tower to the Demiurge’s Realm but was pushed off course by Guitar, who sought the same goal, and he was knocked off course into Dagon’s Realm. The enraged Dagon sacrificed the merged Skeith and York in a horrific ceremony that allowed the demon prince to absorb their power.
