Reisen Gorge

Reisen Gorge (ライセン) is a canyon that divides the North and South portions of Tortus. It runs anywhere from 1 kilometer deep at its more shallow ends, to 2 kilometers deep in certain places. It can span anywhere from 900 meters to 8 kilometers wide, depending on the area, and it runs all the way from the Gruen Desert in the west to the Sea of Trees in the east

It is used as an execution ground since magic can not be typically used inside of it and since there is an abundance of strong monsters. It is the place where Miledi Reisen's labyrinth and the exit to the Orcus Labyrinth is located.
