You Wake Up In A Bar

Mm. Was going to suggest a simple lobby+anchoring vault to start with... But, I thought of a better idea.
What sort of... Ideals, I suppose, do we want to found this space on?
I'm thinking we take those, and turn em into a hotel-tree seed. Make some nice land to plant it in, and give it some Water/attention for it grow.
After the first room, the lobby, it should grow on its own during the day. And at night, we can come back, see the cats, and check out what effect the daily experience had.

I definitely prefer the idea of having a space that's not static/entirely frozen without Greene to exert influence on it. Somewhere Greene isn't needed, per se, but where he's always comfortable and welcome.
