We find a dark (not actually bottomless) pit. We leave a couple of crows with a gatling gun and a magic sword.
We notice the tunnel seemed to have been dug by a large animal.
We eventually come to a place where the tunnel goes under water.
I cast Breath of Life and try to swim in.
I swim and find a “beach” with crystals that are actually shadow creature eggs.
Head back.
We are not swimmers.
Eventually we get back out (at the start of the water). I run a rope, tie it off and people pull themselves alone.
We manage to get to the other side.
We wander the labyrinth. We find a red egg and take it away. The crystals are fighting us (magically).
we end up giving the egg back.
