Ore rich walls. Underground rivers, lava pools bordered by obsidian beaches, and in the center of this hellish landscape is a massive portal to another world...
Located at the bottom of a cave system under the Grove Watchtower, Licnesed2Hench discovered these deep caves while searching for Dungeons. With an abundance of both Lava and Water much fun was had building a portal using the cast in place method.
Later on the immediate area was converted into an obsidian farm.
You need lava? You need obsidian? We got tones of it down here!
But be warned, sometimes things crawl down out of the dark caverns above...
