Never heard of them, but I feel this is likely just a mash-up between blue wizards and the concept of free easterlings. The latter was fed by the later works of Tolkien in which he suggested the blue wizards had been send out to the east in the second age and were succesful in their mission. TolkienGateway provides some brief summarizing info on this, spread over various pages on related subjects.
