This extra dimension occupies a barren place.
This place itself is barren and have no people inside it or any living creatures other than some monster nest and dungeons.
It is a valley.
Specifically, the Valley of Geysers. It is a geyser field on Kamchatka Peninsula. Before the Fall, it has the second largest concentration of geysers in the world.
It is six-kilometer-long basin with around ninety geysers and a lot of hot springs.
Situated on the Russian Far East, predominantly on the left bank of the ever-deepening Geysernaya River, into which geothermal waters flow from a relatively young stratovolcano, Kikhpinych.
Before the Fall, it is part of the Kronotsky Nature Reserve and incorporated into the World Heritage Site "Volcanoes of Kamchatka"
The valley even before the Fall is difficult to reach, with helicopters providing the only feasible means of transport.
