Fissure of Oblivion 

 Event Dates: January 11 – February 1  

Memories may live on only in our thoughts and dreams, but in Atreia, there is always a chance that they become more than mere shadows…” 

Fissure of Oblivion is returning to Aion once again, and with it comes the opportunity for all Daevas to participate in the battle for the Tower of Eternity. However, this battle is anything but binary: Daevas will earn a score depending on the magnitude of their victory or the depths of their defeat. See below for full details on how to enter, and the rewards you’ll reap by participating in this time-limited event!

Battle for the Tower 

After entering the Tower, Daevas will take the form of the mysterious and powerful Archdaeva – chief warrior of Aion’s hosts against the Balaur. As the Archdaeva, they will wield several unique forms which will allow them to command the elements: 

  • Avatar of Fire 
  • Avatar of Water 
  • Avatar of Earth 
  • Avatar of Wind 

Each Avatar form has its own unique skills and strengths. Leveraging their powers will earn you a faster completion time and greater rewards. In addition, slaying additional monsters within the battle for the Tower will also net you additional points. Finding the right balance between slaying monsters and moving quickly will net you the best possible rewards. 

At the conclusion of the Fissure of Oblivion, you will face the Shadow of Oblivion. This mysterious, inscrutable force is determined to stop you from witnessing the truth hidden behind this battle. 


Daevas will earn rewards based upon their clear time and score, up to a maximum of four Sealed Memory Bundles per instance completion.
