Requiem



This unidentified planet, commonly dubbed as the "Legendary planet", is a mysterious Forerunner planet located in the Milky Way galaxy. The aft section of the, containing John-117 and Cortana, is seen drifting in the Legendary ending of Halo 3; seconds later, a light shines across the surface of the planet, as the Forward Unto Dawn is caught by the planet's gravity. The Legendary planet also appears in a small image in the Halo Encyclopedia, where it is shown to have a reddish-orange color on a small illuminated section. The planet appears again in the Halo 4 Announcement Trailer, where the aft half of the Forward Unto Dawn is seen being pulled into a massive, iris-like opening on its surface.

Background
The planetoid is littered with blue-glowing symbols and geometric patterns - clearly Forerunner in origin. At least two of the symbols are clearly recognizable.

The surface of the planetoid bears a certain Forerunner symbol that has appeared in wall ornamentations on all of the Halo installations, on the surface of the Ark, and on the cover of Halo: Ghosts of Onyx. There are a number of theories concerning the meaning of this symbol, some of which interpret it as the main emblem of the Forerunners, the symbol for the Halo Array and the related installations, or possibly a Shield World.

A Marathon symbol can also be observed on the surface. It is known to be a common Forerunner symbol, used in multiple Forerunner constructs, and also used to refer to a Reclaimer. The Seventh Column symbol can be seen on the Legendary Planet as well.

Speculation on just what the planet is, its purpose, and even its location are varied. Whatever the case, by the Forerunner symbols it seems to have at least been occupied by the Forerunners in the past. Although its purpose and identity are obscure, the planet is an elegant story device meant to keep the series open to future game titles, and leaves the opportunity for John-117 and Cortana to continue their adventures well into the future.

Trivia
An image of the planet is present in the bulletin board of the in Halo: Combat Evolved Anniversary, in a poster for a fictional film titled Dark Planetoid Rising.
