Plot summary
Corwin sulks in Castle Amber's library while Oberon gives the family orders. Random persuades Corwin to leave, but they encounter a real-life scene mirroring Corwin's earlier experience in Tir-na Nog'th: prevented from interfering by an invisible force, they watch as Corwin's sword appears and chops off Benedict's new arm.
