Secrets from the Caves of Mother Thrune Fang
A close inspection of the eastern wall reveals that the carvings there are words written in Aklo. They read, “All glory to Great Ydersius.”
The walls of the chamber are carved with images of anthropomorphic serpents using strange, pointed megaliths of stone to work great feats of magic—transforming an army of humans into zombies, calling down flaming bolts of lightning from the stars, or parting the waters of the sea to dash human ships upon the exposed rocks of the seabed below. This final image seems to have been recently cleaned of dust, and several lines of text have been made more legible via the application of inks and perhaps blood.
“To Command the Very Tides to Rise Up and Eschew What Lies Below:
Empower the Four Sentinel Runes with the Blood of a Thinking Creature Tempered by the Kiss of a Serpent’s Tongue.
Anoint the Tide Stone with Waters Brought from the Sea in a Vessel of Purest Metal.
Invoke the Lord’s Sacred Name to Wrap His Coils around the Sea Itself that He Might Lay Bare What Lies Below and Cast Down Your Enemies on the Waves above.”
