This arched subterranean structure, guildhall of the Golgari Swarm, is elaborately decorated and gilded, a sign that it used to be a cathedral of the Orzhov Syndicate. Surface dwellers whisper of how the cathedral was beautiful, once. Its curved arches and stony towers glistened with obsidian and silver in days gone by. But the wear of centuries left it cold and damp, heavy with the smell of staleness and soil. Svogthos is a semi-living structure in which the severed head of Svogthir is believed to be housed. Sometimes called the Restless Tomb, it is rumored to move as the center of Golgari territory shifts.
