Marble Chest

Nothing marble-specific. It draws from the same table a gold chest does, so opening one is a lottery ticket on the standard underground utility items rather than anything the biome owns. Marble caves are quick and cheap to clear compared to granite, which makes their cabins some of the easiest chests in a run to reach.

Pick it up once it is empty. The clean white marble furniture set is slow to build in bulk any other way, and a world only generates a handful of these. If you want a matching row of storage in a base, the found ones are a much faster start than crafting from nothing.
