History of Daemon

Daemons are a unique variant of Proxies found in the Infinite Forest on Mercury. They are Major-tier enemies of the Sol Collective (Gatekeepers) and act as passage keepers. When a Daemon is present, the door to the next area turns red instead of white, and it stays locked until every Daemon spawned for that gate is killed. A "Forest Pathway Cleared" message then confirms the gate is open. Several Daemons can spawn at once.

Daemons come in versions of Fallen, Hive, Vex and Cabal units, including the Encryption Daemon, a Hydra variant. They first appeared in Destiny 2: Curse of Osiris. The name is taken from the computing term "daemon." Destinypedia does not classify Daemon as a boss.
