Deep in the swamps of the Shadow Marches, at the end of the rivers feeding into the Zarash Bay, Zarash’ak is the capital of the orc nation. It is home to the main enclave of House Tharashk and the Shadow Marches Triumvirate. The city is the largest single trade point for Eberron dragonshards, but because there are so many small ports along the coast of the Marches, it is not a particularly central point. The 6000-person settlement is known as the “City on Stilts”; the water levels on the river vary wildly, so raising all buildings keeps it from being swept away.
