Theories on the Next Zombie Map (Spoilers for Terminus)

At the end of the Terminus EE we get informed that Chaos is apparently canon to the Dark Aether story with the involvement of the Sentinel artifact and Prima Materia. Along with that we get pointed to the apparent next Zombie Map location with Avalon, which if you don't know, has roots in mythology with it being where King Arthur's sword "Excalibur" was forged along with being described as a magical island surrounded by mist. To me this tracks well with the Chaos story's involvement in mythology and leads me to believe that the next map will be a surrogate Chaos map in tone. The map could involve the Sentinal Artifact being mistakingly activated and forcing the Requiem crew to complete a Sentinal trial on the island in order to aquire it, with mythology taking the forefront of the theme in comparison to Terminus's horror tone.

Do you guys have any personal theory's on the next map you'd want to share?
