The Nulag River originates in the peaks of Khazandulud. Flowing southward through the valley of Irazaggumak, it enters the mountains of Khizunul, where it becomes a series of turbulent rapids, navigable only by canoe and small rafts. Once past the mountains, the river broadens and slows. From the riverside towns and villages of the Hjalmarbrodd to the bay of Tarag-Khâlu, the depth is sufficient to accommodate even large, giant-built ships. The formation of these deep channels is attributed to the efforts of giant mud crabs, known as Ibelgas's Chariots.
Their meat, a delicacy across numerous realms, they are genuine terrors to witness. Their shells have been transformed into shields as formidable as iron, while the larger ones have been fashioned into rune-etched tower domes, resistant to both psionics and magic. Once the shock troops of Ibelgas, they now thrive as crustaceans naturally should.
