A first-person dungeon prototype set in a vast canyon, built as one dungeon in a larger world.
The dungeon is themed around dirt, which is where the name comes from: lutum is Latin for dirt. It's one of several themed dungeons in a wider world, alongside water, fire and wind, so players keep meeting new enemies and environments.
Its native enemy is the Magnus turtur scorpii, a fast crab, turtle and scorpion hybrid that punishes players who slow down.
