The Omkar Range (ओम्कर् श्रंखला) is the smallest string of mountains in Aurobin-dô. It forms the eastern border of South Aurobin. The range is home to relatively few dwarves and relatively many giants. The large concentration of giants in the Omkar Range may be the reason that the Aurobin Kingdom never spread further east.
Despite its size, the Omkar Range has had a large impact on the culture of surrounding societies. According to orc tradition, much of the mountains were leveled in a battle among some of the oldest gods. Elven and halfling folklore both share a story that suggests that the entrance to Hell is in a crater at the top of one of the mountains.
