In We're Not Worthy, Wade "borrows" the sword and takes it with him to the first ever Salvatore School Field Day to LARP. Unfortunately for him and the other students, the newly released Malivore monster was the Green Knight. In search of the sword ahead of him was Nimue, the Lady of the Lake who was the sword's protector prior to being consumed by Malivore. She is bound by duty to find the sword and a worthy champion to wield Excalibur and defeat the Green Knight.

Rafael attempts to return the sword to Nimue, but she explains that the sword was rightfully his, as he is a descendant of Arthur.
