ASTA will be making a return sometime in the balance of this month. The game will be published by Move Games Co., Ltd. and will be part of the Steam library. You may remember that ASTA was shut down by Webzen in the fall of 2016.
According to the Steam page, new registrations for the game will receive a welcome package with lots of in-game items.
You can check out the ASTA Steam site for more information.
