From official forums:
1:12 PM PST Update: Adventurers, we have a big update. We are making the decision to not only open Reckoning as our NA Fresh Start server, but we will also be opening ONE ADDITIONAL Fresh Start Server: Vengeance. Can't have Reckoning without Vengeance. The overwhelming support players have shown ArcheAge North America has allowed us to do this.
Guilds, please make your decision on what server to roll on now. We are giving you a few hours to prepare yourselves accordingly and communicate amongst your officer staff and members. Vengeance and Reckoning will be the last servers to be opened, and they will open simultaneously.
