This suggestion made me think of Corvo Bianco in Witcher 3.
Geralt retiring to wine country

I don't want to live in a tent forever, but it would be cool if we could have an endgame place (read: castle), where we can display all the armor, weapons and odd-bits-and-bobs (paintings, music boxes, teddy bears etc) we've collected on our journeys. Like this:

Loved how Geralt could invite Jennefer and Ciri and they just wander around. If Tav/Durge could live with their romanced companion, then invite any besties over, that would be amazing :p Give a chance to pen our own invitations, sent by pigeon mail. Mine would say: "Haiiiiii bestie, miss your face. <3 Wanna come over? I have snacks p:"
I would invite Kar'Niss the drider over. He's so sad :c he could use a hug and a friend.
Also Emperor. I'd make sure to get some fresh brains, just for him :3
