The Bannuseyd Mountain range runs along the northern Del’undan coastline, both east and west. It forms an inverted V shape which curtains the Kwandin Valley within. The respective sides of this V are called West and East Bannuseyd. To the south, the mountains collide with the Turrothae Fold, incidentally forming a complete loop. The south-western arm is semi-volcanic, with the greatest of these volcanoes forming the Gates of Fire.
