Miles

Miles is a man found at the Grand Exchange who, along with his brothers, Niles and Giles, provides a tutorial of the bank notes system. He was previously part of the Certer Random Event, where he and his brothers asked players to identify an item, such as a fish. In Runescape Classic, he was found in Draynor and could convert Iron bars, Silver bars, Steel bars, Gold bars and Mithril bars into Certificates. Watto had the same features but was located in Zanaris.
