Forgotten Caverns #1
You’ll find this Raven perched on top of the column featuring the rune bells for the Nornir Chest puzzle, left of the beach.
Forgotten Caverns #2
When the water level drops for a second time at the Lake of Nine, return to the Forgotten Caverns via the back entrance and climb the wall to the top. Turn around and look back down where you climbed to spot this cheeky Raven peering up at you.
