The Crest of Mercury is an obtainable artifact. It is described as, "An iron rod, shaped for the Roman messenger god."
- The crest is named after Mercury, the Roman messenger god. The shape of the crest offers room for confusion, as it is a combination of Mercury's staff (the Caduceus) and the symbol for medicine (the Rod of Asclepius).
