Ruined Atoll

The Ruined Atoll is an area to the south of the Overworld in Tunic. It contains a pathway to the Frog's Domain in the northeast corner. Venerating to the tombs in the four corners of the atoll and then to The Heir statue at the center activates the teleporter that leads to the Great Library.

The Spectral Seller is found in a cave after going down the right set of stairs from the Check-Point, then heading right then up into the wall.
