Skullius left the College of the Esteemed despite his 'nurses' insisting that he take some time to rest and receive further treatment for his gruesome injuries.
Seeing the awkward smile etched upon the unnatural face they had grimaced at when he was first admitted for treatment made them reluctantly let him go as unlike most people he was someone who was actually trying to contribute to the nation by fighting the monsters from Clusters.
Of course, the reason they were still alive even after helping Skullius was because they had been called to deal with a man who was grievously wounded so suddenly when they had been trying to find out if any of their relatives were harmed in the fire.
Some of them even had a uncles that had been killed but the terms of their agreement with the College stipulated that they had to respond to and all duties.
