The Caduceus is the staff of the Olympian god Hermes and the Roman god Mercury.
History
It derives its power from worship, and needs to be charged at temples. However, if there is no good faith, it can drive Hermes mad.[1]
Hermes can change its size[2] and create smaller duplicates of the staff that can locate the main Caduceus.[3]
The main power of the Caduceus is transportation. It aids the god in his duty as Psychopompus, the conductor of souls. Others can wield the staff, but only with Hermes' blessing. It grants the wielder the power to teleport themselves (and passengers).[2]
