Lucifer (main universe), was making rubber ducks, when suddenly he got teleported into a room, and bonked his head, he rubbed the back of it and looked around. And to his shock, there were a bunch of versions of..Alastor? Great, just great, there was a female version, 2P Alastor, Cat Alastor, human Alastor, Alastors from different AU's, ect. And they all looked confused and looked at Lucifer on the ground
Human Alastor: ...the hell-!?
Female Alastor: confused to see him (since she's used to the female version of Luci)
Cursed cat Alastor: meowing confused, (being used to the cat version of Luci)
2P Alastor: just being sad as usual
(Theres multiple other Alastors there besides them, but I'm too lazy to add them in, but you can choose what AUs their from or whatever)
