Giles

Giles is a man found at the Grand Exchange who, along with his brothers, Miles and Niles, provides a tutorial of the 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 ore, Coal, Silver ore, Gold ore and Mithril ore into Certificates. Jinno had the same features but was located in Zanaris.
