Grey Wizard is an Empire hero unit. It is best not to speak ill of the Grey, for they are everywhere and nowhere all at once.
The Grey Order is the most secretive of all the Colleges of Magic. Indeed, though its members refer to themselves as Grey Guardians, just who, or what, they might be guarding remains unknown to outsiders. The Grey Order studies spells of concealment and illusion, which do not lend themselves well to the favour or ordinary folk. They are sometimes called Trickster Wizards, though never to their faces. More commonly, they are referred to as Grey Wizards, named after the colour of their robes, hats and wild, wolfish beards. They are wanderers who are often employed to deliver vital messages across the Empire. What makes this so mysterious is that they seem to cover the vast distances involved almost invisibly and at impossible speed.
