Pirate Stronghold

The Pirate Stronghold is a mini-dungeon featured in SS undefined. It served as the headquarters of the gang of pirates led by Scervo who took over Skipper's Sandship that protects Nayru's Sacred Flame.

Features
The Pirate Stronghold is one of the many islands spread out along the Lanayru Sand Sea and is the headquarters of the pirate crew who took the Sandship from Skipper. It is first visited by Link and Skipper when they are looking for clues to help them find the Sandship. Skipper notes that, while the Stronghold is as scary as he thought it would be, the pirates within should all be dead.

After entering the interior of the pirate's base, Link finds a Timeshift Orb. The orb functions in the same manner as a Timeshift Stone, shifting the surrounding area between a past and present state. However, rather than remaining stationary, Link can pick up, drop, and move around with the orb, giving him access to a series of puzzles. At the end of the mini-dungeon he installs the Timeshift Orb into a generator. As a result, the gigantic mouth outside of the dungeon opens, revealing the remains of the Sandship. After analyzing the wreckage of the ship, Fi is able to dowse for it. With that, Link and Skipper set sail once again to track down the ship.

Trivia

 * There are 3 Silver Rupees within the "nose" of the stronghold. They cannot be obtained after the mouth opens.
 * Despite being located very close to the Lanayru Shipyard, the Pirate Stronghold cannot be seen from Skipper's Retreat, with a giant dust cloud being seen instead. However, Skipper's Retreat can be seen from the Pirate Stronghold.
