"After the events of Time Spiral, Karn was believed to be residing in Mirrodin's Core, being worshipped as the new Father of Machines. When Phyrexia invaded Mirrodin, Karn has been revealed to be slowly corrupting to Phyrexia, although the process is not complete, and it's success is tied to who wins the Phyrexian invasion of Mirrodin."
"In the Mirrodin Besieged set, Karn reappears, infected by the Phyrexian ichor, as the new "father of machines," leader of the Phyrexians. His body has fused to a throne at Mirrodin's core, and his mind has fractured, making him vulnerable to the machinations of his supposed underlings."
