The ancient writings can be found by inserting 100 numulites into one of the stone chests inside the House on the Hill on Fossil Island. There is a chance nothing will happen or a spike shooting out and stabbing the player for 9 damage, wasting the numulites.
This note can be added into the Fossil island note book.
The Zygomite experiment and its effect on location could be explored here, if the spore colonies could be removed in part. Part of me is jealous of the union, I feel alone. My work keeps me sane.
