An emissary is created when a human dies without fulfilling one of their strongest desires. At their death, the High Ones can choose to create an Emissary based on that person. Note that the person is not revived, the newly-created emissary is a completely separate being.
An emissary is physically identical to the human it was based on, and has all of their memories up until death. Psychologically, however, the Emissary is an idealized version of the human whose only goal is to complete their unfulfilled desire. As The Black Guardian said, "They are tailor-made [to the desire]. [...] A broken soldier will become a charismatic and brave leader, ready to lead their men into victory".
The emissaries do not age and are affected more slowly by the cleansing light.
These emissaries are offially confirmed to exist:
- The Emperor, who leads the quest to destroy the High Ones, but ultimately triggers The Cleansing. (In the current iteration, Grandmaster Tealor Arantheal)
- The Prophet, who uses their extraordinary power to aid the Emperor in their quest. (In the current iteration, The Prophet)
- The Messiah, who opposes the Emperor and ultimately forces them to trigger The Cleansing. (In the current iteration, Taranor Coarek)
These emissaries are never explicitely confirmed, but are heavily implied to exist:
