 Eventually all the challengers die except Karsa and Icarium.Karsa fights Rhulad and severs Rhulad's sword arm, then uses all his ghosts and the ones in Samar's knife to manipulate the sword's power and travel to the Crippled God's island.There he flips the Crippled God's tent, slays Rhulad with finality, slaps Withal and enters a portal aimed vaguely at his home after refusing to take the sword for himself (which was apparently the Crippled God's plan ever since Karsa left Laederon).
