This is a Java modded server for players 16 and up. It is built around a custom mod called Descent into the Realm Forsaken that the owner is making for 1.21.8.
Right now the server is mainly for testing before the next big update. People play to try new stuff and help spot issues while things get added.
If you want a fun place where changes happen during the season and everyone is cool with testing then this one fits.
