Fantasta Mountains

From FrathWiki

The Fantasta Mountains are a volcanic range along the southern shore of the Kalpanian Sea (formerly known as Fantasta Sea, the source of the range's name). The Fantasta Mountains are being formed by the subduction of ocean crust underlying the Kalpanian Sea. The mountains have traditionally formed an important connection between North and South Odirá, as they are lower than the Eastern and Western Barrier Ranges, and have passes that are usually crossable. However, during cold periods of Galhaf's history, the passes were snowed over, and the overland route was wiped out.

The re-opening of the mountain passes after a minor ice age played a crucial role in the establishment of the Fourth Kasshi Empire.
