P3X-527 is a planet in the Milky Way galaxy with a Stargate. It was home to the Halkyon and was ruled over by a Goa'uld.
History[]
The planet was scouted by the team Phoenix-5. Although initially deemed safe and habitable by the survey team, the planet was subsequently bombarded from orbit by a Ha'tak, which left it uninhabitable. (RPG: "Core Rulebook")
