Almost a billion years ago, NCSoft announced that they would be migrating accounts for Lineage II and Aion players under a single new log in system. The new system, creatively titled an “NC Account,” consolidates usernames for both services, allowing users added security in the form of a changing user handle, as well as the ability to unify both games under a single NCoin coffer. In order to hasten account migration, NCSoft has offered account holders a bonus 400 NCoin for making the switch.
Migrating is easy, simply log in at ncsoft.com and the process will begin immediately. Simply follow the steps and make sure to use your 400 coins as quickly as possible, as they expire after 30 days.
