Weather-change device is the device that the planet Gallicia has in Temple of Il-Sheen. The device resembles a Touchstone to Madrona. This seems to be a 0.75 m diameter sphere suspended in a magnetic field, which is held within a hollowed-out 1.5-m wide podium inside the Holy of Holies in the Temple of the Storm to Gallicia. The globe appears to be made of a polished slate blue basalt, with an extremely detailed and accurate toppgraphical 3-D image of Gallicia's continents etched and cut into its surface. The podium for the device is made of the same material, with a series of prayers etched around the edge of the podium, and finger-sized holes for control, with sapphire gems set in the sides. The power source for the device is not immediately visible, but in some studies is identified as a large sapphire gem, similar to those in the podium, in the floor underneath the device. Above the planet, there's a network of gemstones set in the ceiling with silver thread tracing linking them. (RPG: "First Steps: The Stargate Unexplored Worlds Roleplaying Sourcebook")
