Technological achievement
The original university was constructed of timber and stone and wasn't rebuilt with Kurete until 1525. By this point, Kuretians had a good enough grasp on the arcane that some of their most accomplished transmuters could shape Kurete to their will. The Royal Palace had long been crafted with the substance and held a large reserve of the material in its cellars. With the existing queen's blessing, the university was allowed to reform the university in Kurete - increasing its size and capabilities greatly.
