Point of Interest: The Blue Room (a Cave-pril creation) (Patreon)

Following a tunnel downward, you discover a small cavern completely lined with millions of bright blue crystals.

The crystals are hydrated copper sulfate. Don't lick them or drink the water you find in the pool in the middle.

One of my kids did a crystal growing science project years ago for school. I've still got the jar we used in my garage that has some of the blue crystals in it.

This underground space was created for day 9 of the month of Cave-pril.
