The nest of the legendary bird, the Roc. A single Roc egg is large enough to feed a whole town for a full lunar cycle. However, not many people are brave, or stupid enough to try and steal an egg from the nest of this giant bird.
Very simple to find, this discovery is on the island directly west of the Will o' Wisps, and furthest towards Ixa'taka. Below the island is a fragment of mountain-coloured rock. The discovery is between a curved C-shaped forest on the island.
