Alright so here's the A plan:
- It's a door.
- Inside the door there is a vast cave system.
- The cave is inhabited by humanoid entities.
- Because the cave has no natural light the entities have a heightened sense of smell and they have no eyes.
- The humanoid entities are sensitive to light.
- The cave to also be inhabited by (possibly corrosive) thick sludge (unsure if its sentient).
- The humanoid entities can climb the ceiling of the cave and are extremely aggressive and agile.
Any suggestions are obviously welcome.
P.S. If I did something wrong let me know, I won't make the same mistake again.
