Urabrask
Urabrask the Hidden is the Red aligned praetor of New Phyrexia. As his name suggests, for much of the storyline his motivations were vague, leaving him as the most mysterious praetor.
His flavour text quotes 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 disagress 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 planet, which is controlled by him. This is due to the fact that he is aligned with the colour of emotion and freedom, granting him enough empathy to not destroy the mirrans. This, coupled with sheer dislike of the other factions, led him to seal the Furance Layer of the planet to other phyrexian factions. For the most part, they don't seem to care either, with the exception of the Blue aligned Progress Engine, which is paranoid about this.
