Holy Grail

The Holy Grail was an ordinary looking blue cup that had held the blood of Jesus Christ.

According to legend, Joseph of Arimathea brought it to England and buried it. A spring formed after he did this. Only the pure of heart could find it. The knights of King Arthur searched for the Grail, but it was found instead by Godric. Soon after, he was lured into a tree by a dryad. Godric and the Grail remained there for a thousand years, finally released in 1936. The Grail caused pain to anything impure or unnatural. It was used by Harry Sullivan to stop Hester Stanton's magic from turning the land of England itself against its people so her son could become king. The Grail fell into a chasm with Stanton and both were swallowed by the earth. (PROSE: Wolfsbane)
