This generator is adapted from the original blog post by Konsumterra.
A much more thorough description is at the orignal blog post, but here's an extract:
So caves are not such a big leap from sewers and i'm still on a bit of a Veins kick. I studied prehistoric rock art and wrote way too much about it so all this inspired me to do this. Mostly they are for decor or curiosity with no game function but villagers might mention them as a scary place or finding one in a deep cave might be a warning. Could describe historic event and you might find remains of a monster depicted in art or find a living descendant.
You might find these in caves but also on cliff faces or anywhere with great sheets of rock. Some might be flooded over by the sea or visible at low tide or on a mountain top.
Was subsequently shared at r/d100.
