supposedly people from nostalrius team are joining elysium project, as far as is known nostalrius will be reborn with 3 new realms
1.fresh start pvp realm, 2.pvp realm(using nost pvp database), 3.pve realm(using nost pve database)
the last save of progress on elysium server was 6. november, so progress you make there after this date won't matter, and the saved progress will merge with the realm 2. nostalrius-pvp-database when it launches, it also means you can play old nost characters on this realm if you had any (or on the pve database realm)
date of launch is to be announced in future, and some announcement is to come this weekend
that is what has been told to me or what I read from announcement/forum, there may be some news that I don't know of
elysium announcement is here
