Song Description
It starts with a low note by orchestra, quickly followed by a choir melody. This melody is almost the same as the Gregorian-style chant from the Halo Theme, but it has slightly different chords at the end of each phrase, giving it a more uplifting mood. The music rises, then at 1:10, drums start their section of soft-soft-loud beats. Later, low wind instruments play a few notes. Following is a section the same as a part of Farthest Outpost, composing mainly of low wind, drums, and orchestra. After that, drums take over again, with orchestra playing background melody, in a remix of Under Cover of Night with the In Amber Clad bassline. At 4:00, a more minor melody takes over, mainly by piano. The piano melody continues to swell, then fade again. The melody speeds up at around 5:30, then slows again. The last note is played by high strings.

This song runs for 5 minutes and 57 seconds.
