I might be wrong but the way I pieced it togehter, is:
One of the stonemasons who's notes you can find in Reithwin seems to have been the architect. He later on saw the error of his ways, made a deal with our best devil to destroy the Sharans (which Raphaels subcrontracted to Yurgir) and ended in the House of Hope, where you can chat with him and tell him about his tower.
