Sorry for double-post, but I gots a big theory. Credit to J. Shuster on Twitter for first bringing it up with the Legion totems from Case Files.and
There's something representing each Legion of Horror in the Fear Realm:
- Iniquitous: La Muerte in Monstruos.
- Strengoits: Countess Marya (Dracula's Daughter) & Brides of Dracula in Eternal Bloodlines.
- Cerebin: A Quiet Place's Death Angels and the Monstruos.
- Baccanoids: Major Sweets and the Grabber.
- Maschorians: The Demon Queens, and Sinister & Surreal themselves.
- Morphans: The Triplets and Goblins.
- Kerezans: The Swamp of the Undead.
In Case Files, the ending of the house was Tim Foyle accidentally opening a portal into a hellish world when he brought the Legion totems together, and Sinister & Surreal's lore reveals that the creation of this realm began with the first Fright Nights in 1991- "For 33 years, the screams of thousands of eager Halloween Horror Nights guests have been collected within the shadowy depths of Universal Orlando Resort." The ending of Case Files took place on the first night of that event.
Could this be a realm for the Legions? After all, they are the Legions of
Horror and this year's tagline is "Where Horror Lives".
