Reisen Gorge

Reisen Gorge (ライセン) is a canyon that divides the north and south portions of Tortus's mainland. It is the place where Miledi Reisen's Labyrinth and the exit to Oscar Orcus' Labyrinth is located.

Layout
Reisen Gorge runs anywhere from 1 km deep at its more shallow ends, to 2 km deep in certain places. Depending on the area, it can span anywhere from 900 meters to 8 km wide, and it runs all the way from the Gruen Desert in the west to the Sea of Trees in the east. There are staircases at each end of the gorge.

Reisen Gorge's most unique feature is that Magic can not be used inside of it. Furthermore, it is the home to an abundance of strong Monsters.

History
Throughout Tortus's history, Reisen Gorge has been used as an execution site.
