Anathema is the old Nostalrius PVP server, which means that it’s further progressed and has more level 60 characters and more guilds farming raid instances. On June 21st the Zeth’kur realm was merged into Anathema.
Light’s Hope was created when developers and team members for the Elysium Project staged a coup d’état, releasing multiple screenshots and information about gold and character selling being done by other members of the team. They made fresh backups of all of the servers and sabotaged everything so that the remaining Elysium team wouldn’t be able to restore the servers easily.
They have the same three realms as the Elysium Project, so if you already had an account at Elysium it will also work here. All realms are set at x1 experience rates.
