Not sure what other mental upgrades she could get, since she is having issues there as it is, but maybe that is where A11-y will shine or something. This is also partly what the partitions are all about, hopefully Archon won't be able to get in there, or we really will have a war on our hands faster than we want.
Well, a number of us have been discussing going underground for some sanctuary expansion. The thing about going higher was just that Runey didn't feel he could juggle that many more stories at this point.
We certainly need at least another room for beds in there.
Hard to say for the fairies, Ash would need a new roommate, and they would not be able to relax as well, since they would have to worry about others watching them. XD
As for the garden, we will be able to grow things there at some point, for more income. Food, tinu, etc... Though, at some point, we might need that to help us survive. lol
Yeah, I have always been a fan of hers. Sadly, her not getting content had become a running gag, like people forgetting who she is.
Eris is more likely, there have even been some hints about her wanting to move out of her parents' place.
