Urabrask's History
Urabrask, the Hidden, is the red-aligned praetor of New Phyrexia and commander of the Furnace Host. As his name suggests, for much of the storyline his motivations were vague, leaving him as the most mysterious praetor. His current status is unknown.
All information about Urabrask seem to imply that his intentions during the Phyrexian/Mirran war (and possibly his current intentions as well) were to turn Mirrodin into a form that he considers perfect, making him similar to his rival
Jin-Gitaxias in goals, although very different in methods and most likely in the end result. Also like Jin-Gitaxias, he uses an alternative term to "Grand Evolution", the "Great Work", although whether he actually disagrees with established Phyrexian terminology is unknown.
After Phyrexia's conquest of Mirrodin, Urabrask allowed the Mirran survivors to take refuge in the furnace layer of the plane, which was controlled by him. This was due to the fact that he is aligned with the colour of emotion and freedom, granting him enough empathy not to (actively) destroy the Mirrans. This, coupled with a sheer dislike of the other factions, led him to seal the Furnace Layer of the plane off from other Phyrexian factions. For the most part, they didn't seem to care either, with the exception of the blue-aligned Progress Engine, who were paranoid about it.
Inevitably,
Elesh Norn laid waste to his domain, though the Mirran Resistance fled to the mountain shelters, out of her reach. He and his red Phyrexians then began dwelling on the Furnace Layer.
Seeking to double-cross Norn, Tezzeret found an unlikely ally in Urabrask, who he transported to New Capenna. The Planar Bridge heavily damaged the praetor's body, searing his flesh from his inorganic components, and leaving him in a severely weakened state. He had been in the city for several weeks, healing enough to survive a return trip. While there, the praetor met with Vivien Reid and tasked her with bringing him Halo and the Planeswalker Elspeth Tirel, claiming that her presence would tip the balance of the war on New Phyrexia in the Mirrans' favor.
Returning to New Phyrexia, Urabrask and his rebel Phyrexian faction openly fought against Elesh Norn, staging their own rebellion parallel to that of the Mirrans (though they do not openly assist them). The rebel Phyrexian faction included the Steel Thanes that didn't bow to Elesh Norn. Later, he helped Chandra and Wrenn, among a squadron of Mirran resistors, reach Realmbreaker.
Soon after, Elesh Norn had him tortured on a rack and chopped off his limbs, but instead of executing him, told her harvesters to “Leave the traitor be.” It is currently unknown if he survived the final battle or his wounds.
