You see a large crystal teleporter.
Location
Edron, Darashia, GCTS, Kazordoon, Liberty Bay, Svargrond, and Thais, as well as Gnomegate, Hot Spot, Truffels Garden, Golem Workshop, Crystal Grounds, Gnomebase Alpha and the Warzones.
Notes
Used to teleport from several cities to the GCTS. The player must have a Teleport Crystal, which is used up like Orichalcum Pearls, in their inventory to teleport. For the warzones, you need a Red Teleport Crystal. Travelling between the other Gnome areas require no crystals at all.
The player must have started the Bigfoot's Burden Quest
You will see the message "You have no idea on how to use this device. Xelvar in Kazordoon might tell you more about it." if you try to use it and have not started the quest.
