// A blacksmith's anvil on a stump, big and filling most of the grid: a thick round brown tree-stump block (about 14 wide, 10 tall) with ring lines on top, and on it a big dark iron anvil (about 26 long): a wide flat rectangular top face with light grey edge highlights, a long pointed cone horn sticking out to one side, a stepped narrower waist and a wider flared foot. A hammer with a wooden handle lies across the anvil top and a glowing orange horseshoe sits next to it. A small wooden bucket stands against the stump. Everything is touching and solid: no loose floating bits, no scattered debris on the ground.
