|Powers the Watchtower in Yanille.|
Crystal is a quest item that appears in the Watchtower quest. As the quest opens, ogres have stolen the four crystals needed to power the watchtower and protect Yanille from invasion by the ogres. There are four crystals, each a different colour, and the player must retrieve them by performing various tasks for the ogres that live in and around Gu'Tanoth.
