The Farseer Device ("Nearscope", "Torantube")

Image description.

The Farseer is a cleverly-designed optical instrument of hobbit manufacture (although credit for its original invention goes to either the gnomes or the dwarves, depending on whose version of history one chooses) and may be found through most of central Sarvonia. The Farseer device is also often referred to as "Nearscope", "Distance Viewer", "Torantube" or "VoholPrawie". Image drawn by Seeker.
