(it was more of a misguided instruction. The Alldeck Arc works in a function like that. it can also be given away. the Alldeck Fae works in suit with that. The Saigra has no true owner. if you have it you can use it....if you know how. the Xalien Arc and Amrash Arc can only be used by the one it wants to use it. all four swords have souls. but of the four souls. only Amrash and Xalien can choose its owner. Nightmare also said she wasnt sure about how they work. She WAS using her best knowledge and making an educated guess.)<br/><br/>*Rabid disappeared before the blade of darkness hit him he reappeared next to Nightmare*
