This idea of killing a Prince in its plane is falacious. No idea where this idea came from. Twice in games has a Prince been defeated in his own plane. Once in Battlespire and again in ESO. However, it is theorized that you can permantently destroy and Daedra by canceling it out with Tonal Architecture.
