PETRIFIED ISLANDS | Alkidas Fort
Riddle Name: Star-Crossed Lovers
"My lover lived in the Petrified Valley and I, in the Ancient Pearl. To Eresos I had to go in order to see my girl. But there was a sonorous crack halfway through, and blue was what I reaped. The wooden behemoth groaned and creaked, and at the bottom of the river we began to sleep."
The Ainigmata can be found inside a building at the fort. Ladder up.
