The one without Free Will.
A world that now only consists of a stagnant, sterile, crumbling Heaven. Lilith never left Eden. New souls stopped being created. Lucifer is alone, unrecognized in a workshop in Heaven. Charlie will never exist.
The world that ended before it had a chance to begin.
I'm picturing a depressing universe without sound or colour. No one is truly sad, simply because no one remembers being happy. Lilith, Adam and Even are still there in the garden, barely concious and just going through the motions.
I like to think the Hotel Guest from that world would be Sera, who is also the catalyst for it's downfall, that her need for 'Order' in that timeline became overbearing to the point of smothering life before it could grow.
When she arrives at Haven, it's like she's seeing colour and hearing music for the very first time- thousand of overwhelming sights and sounds all at once. She sees Haven!Lucifer and doesn't even recognise him as an alternate version of her sibling, who has stopped talking long ago.
The Haven Hotel doesn't just exist as a shelter for the survivor's of doomed timelines, but as place to redeem those universes before they become unsalvagable. I think that world can still be saved, it just needs a little intervention from the outside. A little spark of chaos to get the ball rolling.
