" I was willing to die fighting, but it was senseless for all these men to go down with me. Perhaps my blood was tainted, despite my power over the Pattern. A true prince of Amber should have had no such qualms. I decided then that my centuries on the Shadow Earth had changed me, softened me perhaps, had done something to me which made me unlike my brothers. "

― Roger Zelazny , Nine Princes in Amber (The Chronicles of Amber #1)
