Former Spirit Trapped in the Helm of Sesyphus. Later a leader of the Army of Undeath. A cleric of Wee Jas.
Yekve was a ghost-like undead creature by the time the PCs met him, but before that his spirit was trapped in the Helm of Sesyphus. Before that, he was a handsome blonde man who helped start the ICS some six centuries earlier.
After Kelvin Fesselhoff freed Yekve, Sesyphus’ late brother, from the Helm, the spirit started working to convert Fesselhoff to Wee Jas’ causes. By all appearances it worked. Fesselhoff seems to have abandoned his hubris, his need for power, his greed and converted to Wee Jas’ faith. After doing so, he and Yekve set about creating the Army of Undeath so that they could destroy the ICS.
Little is known about Yekve, except that he was mortal once, some six hundred years ago when he helped found the very organization he would later destroy. He was a powerful cleric of Wee Jas. And somehow he was trapped inside the Helm of Sesyphus.
When the Army of Undeath disappeared into the ocean, Yekve, one of their generals, went with them. As far as anyone knows, he is still alive.
