The post below this one, this, showed a mysterious spoiler. I'm happy to announce that Ardentcraft is now hosting a PVP server again! To go to it you can either type /server pvp or /server and then click the server name you want to join. Another useful command is /glist. This will show you all the players online and which server they are currently playing on.
I hope everyone has fun! Enjoy your time on Ardent.
