History of Calus's Loyalists

Calus's Loyalists are the Cabal forces who stayed loyal to Emperor Calus after he was overthrown and exiled by Ghaul. Destinypedia lists them as a Cabal legion linked to Calus. It says their advanced Harvester variants "would also be used" by the Loyalists, alongside the Shadow Legion and Imperial Cabal, but this link rests on a single sentence.

The Harvester is a Cabal troop carrier that drops from low orbit rather than teleporting, and deploys up to three waves of troops. Destinypedia describes the more advanced Thresher variant, used by the Red Legion, as able to travel FTL. The FTL claim is based on one example and may not apply to every advanced variant.
