NC announced a new Aion 2 Sanctuary on September 9, 2026: Snowfield of Sorrow. The company described it as its highest-difficulty PvE content at the time of the update. The Korean announcement names a new final boss and equipment rewards, making this a target for organized groups rather than a casual first dungeon.
Why the distinction matters
A “new best dungeon” headline does not tell every player to rush in. Look at the current entry requirement, your group's experience and the reward you are actually chasing. If you still need practice with earlier Sanctuary mechanics, an older run may give you more useful progress than repeated failed attempts at the newest encounter.
English names and reward translations may differ between service regions; we will verify the global client terminology before publishing a detailed boss guide. For now, this is a dated news summary, not a claim that the September regional content is already available globally. Source: NC's September announcement.
