To better accommodate the declining population of the private server, the team behind Kronos WoW – Twinstar, decided to merge their old Kronos 1 (I & II actually) and Kronos 3 realms into a single one called simply Kronos.
The upcoming Classic WoW by Blizzard declined the populations on all private servers including Light’s Hope, The Elysium Project too beside Kronos.
The server still maintains active population of around 1000 players, so if you wish to test Vanilla, you can register on the following page.
