Besides Eliot, the members of the quest as described by the Great Cock are: The one-eyed conqueror (Margo), the traveler (Penny), the warrior (Kady), the fool (Quentin), the god-touched (Julia), the lover of tomatoes (Josh), and the torture artist (Alice).
This is the first episode to include "sy fy original" in the opening credits.
At one point, Julia mentions that Quentin had been binge watching the show, Six Feet Under (2001). Judith Hoag (Stephanie Quinn - though she doesn't appear in this episode) played the character of Dawn in an episode of the show (the episode was, Out, Out, Brief Candle (2002)).
Stella Maeve (Julia) and Jason Ralph (Quentin) have both appeared on the original Gossip Girl (2007), albeit in different seasons so they never had any scenes together. The show then got a revamped version, Gossip Girl (2021) which aired 9 years after the original ended. Jason's wife, Rachel Brosnahan has worked with Luke Kirby in the TV show The Marvelous Mrs. Maisel (2017). Luke played the character of Davis Calloway in the revamped version.
