There was a relay I paid to join that had a filter like nostr wine that had universe in its name. I just can't remember what it was called

I’m interested now too. Writing an article on relays now.
This one also looks cool: https://nostrich.land
did a search on https://nostr.watch/relays/find#all and couldn't find a relay with universe in the name.... aaaaaaand it's gone.
Relays are still unchanged territory.
