From MIwiki
The Mysts o' Tyme Marshe is a geographical feature of the interior of
Lucre Island. It is an eerie location, full of thick gray mist, dead trees, and the skeletons of old wrecked boats. The water has a distinct pungent smell, and is deep enough that it can only be traversed by boat. The marsh has been cursed, so that nobody is able to navigate it without becoming hopelessly lost. Its name comes from the fact that time varies according to location inside the marsh, which can lead to paradoxical events like meeting your future self.
Pegnose Pete is the only one who has been able to navigate the marsh successfully, and has used this fact to avoid capture. His hideout is hidden deep inside the marshes.
Trivia
- In a tribute to The Empire Strikes Back, one of the screens in the Mysts o' Tyme Marshe has a half-submerged X-Wing.
