"WE'VE GOT A NEW CONTACT, UNKNOWN CLASSIFICATION!" This article may contain information based upon upcoming, unreleased, or recently-released content, and may not be fully complete.

Greydowns was a human colony planet. At some point during the Human-Covenant War, Covenant forces under Supreme Commander Thel 'Vadamee attacked and glassed the planet.

Production notes

While stated to be a human-colonized world glassed by Thel 'Vadam's forces, Greydowns is clearly depicted as a gas giant; the planet is virtually identical to Jupiter in particular. While this may be a production error, it is possible that the colonies were located on the planet's moons, similar to the human colonies in the Jovian Moons.
