- "Isla Fortuna is a small island. Difficult to find. Not everybody is as good at navigating as me and Tumen. Maybe all the ships are lost out at sea looking for it."
- ―Jean Magliore
With the Sword of Cortés in his possession after stealing it from Isla Esquelética, Left-Foot Louis and the crew of the Cutlass docked at Isla Fortuna to find an incantation that would allow Louis to free the spirit of Hernán Cortés. The incantation had been written on a parchment held by Francois, who was buried on the island.
Captain Jack Sparrow and the crew of the Barnacle were directed to Isla Fortuna by the scabbard of the Sword of Cortés, which acted as a compass, indicating the direction of the Sword itself. Upon arrival in Puerto San Judas, the crew found the port empty, with no inhabitants nor ships in sight—vanished by the Sword of Cortés. Jack arrived at the Church of San Judas, where he discovered Louis and his men digging up Francois' coffin in the graveyard. This led to a confrontation in the church, during which Louis was disappeared by the Sword, held by Arabella Smith. Cortés' spirit was subsequently released when Jack read out the incantation and combined both Sword and scabbard.
Cortés taught Jack how to use the Sword, tricking him first into destroying the dock, then creating a river in one of the island's valleys, then causing snow to fall across Isla Fortuna. Jack ultimately realized Cortés was using the Sword for his own ends, and released the spirit of Montecuhzoma to battle Cortés. The conquistador was defeated, and his alterations reversed—including the return of the island's natives to Puerto San Judas. Jack's crew departed Isla Fortuna to give the Sword over to Tia Dalma.
The island was dominated by high mountain ranges and tropical coastlines resplendant with palm trees. Puerto San Judas served as the island's main port, named after Jude, the patron saint of desperate situations.
