The Gumar valley lies nestled between the Netheram mountain range. Despite its bleak and arid nature, devoid of precipitation, the valley is cloaked in perpetual shadow cast by the looming floating island above. During the Lith-Crillion Era, the ancient being Krarkauk sojourned in this desolate locale, and it has remained stationary there ever since.
Gunmar is a haven for creatures of the night. There have been colonies of drow and illithids that established settlements in this region. These groups are periodically cleared out by the cloud and storm giants residing on Krarkauk. The area is also the abode of shadows, vampires, and other undead with a particular affinity for dark and shadowy spaces. Due to the threats emanating from Gunmar, Netheram's frost giants and other humanoids have learned to construct fortified structures with layered defenses, employing various light-producing elements. These places are constantly bathed in the glow of great braziers of burning oil, torches, and magical illumination.
