The Pirate Homeworld is a planet visited by Samus Aran in Metroid Prime 3: Corruption. Originally thought to be the birthplace of all existing Space Pirates, the Metroid Prime Trilogy art booklet stated that it is one of the Space Pirate homeworlds . Though the planet is effectively unnamed in the other versions of Corruption, the Japanese version and unused text suggests the planet is named Urtraghus by the Space Pirates and Planet SN-883 by the Galactic Federation.
Complete Map of the Pirate Homeworld : 
The Pirate Homeworld is plagued by a steady stream of Acid Rain, harming any creature without proper protection. It is unique as it features a Transit system, connecting areas for convenience to travellers on foot. The planet was the first target chosen by Dark Samus to impact a Leviathan onto after taking control of Phaaze with Aurora Unit 313. Space Pirate Data insinuates this occurred long before Bryyo and Elysia were impacted. Thus, the Phazon corruption seen on the Homeworld is more advanced than the latter planets, containing many immense Phazon growths on its surface. The Space Pirates' willing interactions with the Seed are likely to have contributed to the corruption as well. The Homeworld was also protected by a gigantic shield, which Samus had to deactivate in order for the Galactic Federation's assault to commence. When the Leviathan was destroyed, the planet's corruption was stopped.
The planet includes the Command Center, a Research Facility, a Mining Site and the Pirate Homeworld Leviathan. In the Command Courtyard, there are three doors in one room that cannot be opened. It is likely that these doors lead to the Pirate's living quarters. Various large tunnels are present too, possibly allowing Pirate Cargo Drones access to the rest of the base. Samus was able to navigate these tunnels using her Gunship, allowing her to move between the sections of the facility quickly and undetected.
While the planet's most abundant life-forms are Space Pirates, Phazon Metroids and a few other bioforms dwell on the planet as well, such as Shriekbats and Scritters, who thrive in the sheltered areas throughout the Space Pirate complexes, despite the inhospitable weather conditions. Another species that may originate here are the Korakk Beasts. A possible plant that may have grown on the planet is the highly toxic Bajar Grove, since it and the pirates are stated as having alkaloid in their systems. A number of mechanical creatures also reside on the planet, like the Puffer Mines which have been cybernetically enhanced to survive the rough conditions.
A number of deceased wildlife can be found and scanned in various places where Pirate experiments have gone wrong, such as in the Scrapvault, where one such example has been woven into the Pirate structure.

Unused Logbook entriesEdit
- A possible reference to the name "Urtraghus" (惑星ウルトラガス) is found in the name of the Urtragian Shriekbat on the planet.
- The art booklet that is included with the Metroid Prime Trilogy refers to the planet as "one of the Space Pirate homeworlds". Like Zebes, both planets were considered by the Pirates as the homeworld: the Space Pirates on Zebes referred to themselves as Zebesians after conquering it, and the Space Pirate logs refer to the planet visited in Metroid Prime 3 as '[their] Homeworld'. It is unknown how many celestial bodies the Pirates have converted into worlds that befit the title Pirate Homeworld. The true origin of the Space Pirates has yet to be discovered.
- There is a glitch in the room Mine Lift that will prevent progress, forcing the player to restart the game. There are two Spinners in the room, which cause the lift in the room to drop. However, if one Spinner is activated and Samus leaves the room, both Spinners will be deactivated when she returns, and the Mine Lift cannot be dropped. If this happens and the player saves, the game cannot be continued.
- There is a reference to a seemingly lost Metroid game in the Research Facility of the Pirate Homeworld. A terminal in the room Metroid Processing states that "Metroid project "Dread" is nearing the final stages of completion." While in-game it refers to a Space Pirate attempt to convert Metroids into a power source for weapons, this scan is thought to refer to the Nintendo DS video game, Metroid Dread, that seemingly fell off the radar in development; however, the terminal next to it says the project has failed. According to Retro Studios, the reference was not intentional, but this line has caused much frustration and false hope among fans, as Metroid Dread was thought to have been potentially canceled prior to the release of Corruption.
- In the Japanese version of the game, the scan terminal mentioning Metroid project "Dread" now mentions a Dread-Class Turret. The terminal that said the "Dread" project failed references said project without referring to it as such, and still notes that it is not going successfully.
- The theme of the Space Pirate Homeworld later in the game is a remix of the music heard while exploring the underground sections of Crateria in Super Metroid. The song was again heard while in Chozodia during Metroid: Zero Mission whenever Zero Suit Samus is detected by Space Pirates as she tries to find the Ruins Test to grant her the fully powered suit.
- The Pirate Homeworld has the most Energy Cells in the game: three in total.
