The Veilroot Marches are a broad cavern-and-sinkhole homeland of the Broodweb mycnoids, where mushroom forests spread across damp stone and old vaults sleep beneath moss. Communities cling to ledges, tunnels, and forested hollows rather than a single city, making the region feel networked and far-reaching. Trade, ritual, and survival all depend on silk roads, fungal harvests, and careful knowledge of the dark.
