I really would like to have this possibility.
I’ve started this game in 2024 and I just wanted to test the game, so I named my real “Test”.
I didn’t knew I would fall in love with NRFTW and spend 200h+ on this realm. Now, my realm is maxed to the core and still have this shitty name… 
Do you think it could be possible to rename our realm in the future ? My realm is not a test anymore since the breach.
