Covenant rope

The Covenant Rope is a type of rope used by Covenant soldiers to rapidly descend from high places, similar to rappelling rope. They are described as "slithering, plasticine ropes which glow ghostly blue". In 2552, during the Raid of Reach, teams of Sangheili used them to rappel down on the floor of the central room of the Menachite Forerunner Complex below Reach, to recover the Forerunner Crystal from Dr. Halsey and the Spartans.
