Composer's Abyss

The Composer's Abyss is an underground structure on Halo Installation 03 used to store victims digitized by the Composer. Located at the end of the tunnel is a slipspace portal that leads to a Forerunner city.

History
In late 2554 the Composer was removed from Installation 03 and taken to the nearby Ivanoff Station for research by the Office of Naval Intelligence. On July 25, 2557, Spartan Team Black was killed outside the tunnel by the Ur-Didact and his Promethean Knights and Crawlers. Spartan Blue Team was shortly dispatched to the installation, only to discover of Black Team's demise, and soon came across the Composer's Abyss. As they walked down the path inside the tunnel the Spartans discovered composed human essences affixed to the walls of the tunnel, and eventually came across the slipspace portal. The Didact was soon notified by a monitor that the Spartans had found the portal. Upon entering the slipspace portal, they were teleported to the Didact's world.
