You will pry the theory that Orsino never resorted to blood magic & became a ghastly abomination creature made of dozens of dead mages but that Hawke realised it had been him supplying information to her mother's killer & so she snapped & brutally murdered him & Varric made it all up to protect her because why else would that be the only question he disapproves of when you ask him about it in Inquisition out of my cold dead hands.
