I've only got the first two parts of my riddle, first being go to Plunder Valley, the second part is giving me a hard time though.
"Seek the cave mouth beneath the overhang in Canyon Pass, keep a weather eye, it lies in wait for a light held high"
I've been to every cave mouth on the island and held up my lantern to them all, but nothing is working. I've even waited for a storm to pass by the island, thinking that the "weather" needed to be right.
