Mimiron (called Mimir by his friends) is one of the Titanic Watchers. He once resided at the Temple of Invention, but is absent during the time of Loken's rebellion. It is said that his mechanical servants appear to have turned against each other and that several attendants have been piled together in an unorganized manner. The remaining mechagnome guardians were corrupted by an unknown source.
