History of Radial Mast

Overview

The Radial Mast is a paracausal artifact built by the Witness. In the Downfall mission of Lightfall, Emperor Calus and the Shadow Legion use it to attack Neomuna by bringing it into range of the Veil and linking it to the Traveler. Rohan destroys it by detonating himself next to it.

Mission

Players clear Cabal at a golden circle to unlock a Darkness Resonance orb, deliver it to monoliths, and defeat the Champions Calus summons. Guides disagree on the exact sequence, and they date from the Lightfall launch.
