It's the semi-circular floor from the Mithril vignette "An Unexpected Party". While I'm not planning on fixing the figures to the floor (they're actually going to be used in various crowd scenes), I do want to use the floor as perhaps a low stage in a tavern, or in a town square. So not terribly weathered, but not so very pristine as in Aunt Abigail's good parlor that only sees the light of day for funerals or a visit from a head of state.
