The Age of Conan Facebook page has a brief note to let players know that 2018 will see the launch of "Saga Servers". Saga Servers will only be live for a limited amount of time and players can earn special rewards for completing objectives. "All players will start with a fresh new character that will be transferred to Crom after the saga server's live period ends".
Developers are promising to release more information after the first of the year.
Check out the Age of Conan Facebook page for the full announcement.
