The Wand of Water

The Wand of Water is one of the Nine Wands of The Earth. It is currently the only one of the Nine Wands to have appeared in the story so far. It appears to Mary Cassel and informs her of the coming resurrection of Cassandra.

Pre-ASFS
Like all the other Wands, the Wand of Water was created by Merlin sometime in the 1100s. Merlin is seen creating the Wand through the use of the Wand of Creation. At some point, the Wand was placed at Brompton Cemetery, presumably by Mathias, for Mary to find.

ASFS
Mary finds the Wand at Brompton Cemetery, and it immediately begins showing her its creation and warns her of the oncoming danger of the Witches of Old Salem.

Mary uses the Wand throughout the novel. It speaks to her in Mary's mind and helps her come to grips with magic. It also seems to show some knowledge of the future, warning Mary of the eponymous "sacrifice" to come.

Trivia

 * The Wand's morals can be brought into question multiple times throughout the story. Examples of this being Its refusal to disclose information that It does not deem to be important.
 * It is noted that the Wand of Water is one of the least used Wands of The Earth, despite having been recorded as one of the most powerful.
 * None of the Nine Wands of the Earth were in the original story. Only upon a rewrite, was the idea added.
 * How the Wand got to Brompton Cemetery is still largely unknown, but it is assumed that Mathias had something to do with it, seeing as it was he who told her that something was left for her there.
