Knis-Leir, or the "Blue Peak", is the southernmost volcano of Borngring. It is an active volcano that frequently erupts into a wasteland called Hlaeust. The volcano spews more than just lava. It is also a source of gems and blutium. Scavengers of this material are quite common on the slopes of the volcano and across Hlaeust. The fire giants claim that much of the interior of Knis-Leir is made of this much sought after metal. They say the lava tubes beneath and inside the peak are made of blutium, and workmanship of none other than Surtur.
