Vast Suliban Cabal stronghold where Jonathan Archer rescued the Klingon courier Klaang during Enterprise's first mission.
The Helix was a large Suliban Cabal facility made up of hundreds of modules arranged in a spiral around a central axis, serving as a base for the Cabal's operations.
In Broken Bow, Archer tracked the kidnapped Klingon courier Klaang to the Helix. He infiltrated the station, confronted Silik and gained a first glimpse of the Cabal's link to a faction in the future before escaping with Klaang. The rescue allowed Enterprise to complete its first mission by delivering Klaang to Qo'noS.
