Uncharted

Uncharted is one of the islands located in the Archipelagos de Shantar and is south of Docksen. It was originally unexplored due to the danger surrounding the island: no one had gone to the Uncharted and lived to tell the tale until the arrival of the Menagerie.

Environment
A thick fog surrounds the Uncharted, preventing anyone from seeing it from the outside. The island itself is covered in lush jungles and dense swamplands.

Culture
Dinosaurs and lizardfolk call the Uncharted their home. The dinosaurs, in particular, make the land extremely dangerous for any who dare to step foot on it. The Menagerie was the first group to ever set foot on the island and then leave, although Sammy Kozor had been living on the island for fifteen years prior to the group's arrival.

Trivia

 * This island, alongside the creatures that inhabit it, probably exists due to the DM's love of dinosaurs. This theorist, OctoGikai, would need further confirmation on this.
