Mercury is the fastest, hottest and smallest planet of the solar system. It travels very close to the Sun. Mercury is the messenger, the God of learning, communication, travel and trade. He is also a healer and a magician - his mercurial nature gives him power over all the elements and the ability to affect change in accordance with the will. He is a trickster God as well though and master of deception, so his wheelings and dealings may not always be what they seem.
