Kraynox, known as the Deep Thane, is an enormous, multi-limbed black-aligned New Phyrexian whose objectives are bound with the subterranean Mycosynth pillars between the completed Furnace Layer and Mirrodin's Core. He is described as a being coated in oil, and is assumed to be the largest of all the Seven Steel Thanes.
The ideals of Kraynox revolve around the construction of a grand fourth layer to New Phyrexia, woven of organic and metallic structures which form the vast labyrinthine factory. This layer is seemingly entirely industrious, flowing with foul oil and dense with the smog of countless pipes, pools and breathing organic vessels used to extract oil for use elsewhere.
It can be assumed that Kraynox is seeking to rebuild Phyrexia based on visions of the past, idealizing the traditional Phyrexian civilization. To this end he aspires the title of Father of Machines, tyrannically ruling the fourth sphere of New Phyrexia, and awaiting his time to one day emerge after all the other pretenders have defeated each other.
