AION 2 takes place across the world of Atreia, a planet that fractured into two hemispheres in the IP's foundational catastrophe. The Elyos hemisphere of Elysea sits above; the Asmodian hemisphere of Asmodae sits below; and the void of Reshanta, also called the Abyss, occupies the gap between them. NCsoft has stated that the AION 2 world is approximately thirty-six times larger than the original Aion's, totaling around 1,200 square kilometers of seamless terrain.
World Structure
Layer | Description |
|---|---|
Elysea (upper hemisphere) | Elyos faction territory; bright, ordered regions with classical architecture; PvE content for the Elyos plus shared open-world content |
Asmodae (lower hemisphere) | Asmodian faction territory; harsher climates and gothic motifs; PvE content for the Asmodian plus shared open-world content |
Reshanta / Abyss | Contested middle layer of floating islands and aerial battlefields; the home of open-world faction PvP |
Seamless Open World
Travel between regions does not require loading screens for most of the world. The seamlessness is one of the design pillars announced for AION 2, and Unreal Engine 5's streaming systems are used to keep the transitions invisible during normal play. Loading still appears when entering instanced dungeons or specific PvP arenas.
Verticality
Regions are designed with verticality as the primary axis. Cliffs, floating islands, sky-temples, and multi-tier cities reward players who can fly. The same map at ground level often hides paths that only become visible from the air. This design extends into PvE encounters, where many ground-level routes are gated behind aerial puzzles or vertical climbs.
Reshanta and the Abyss
The Abyss layer is the heart of open-world PvP. The Abyss has multiple sub-maps. Lower Reshanta supports full powered flight, while Middle Reshanta (added during Season 3 on the KR and TW servers) restricts players to gliding, walking, or running. Each sub-map has its own contested objectives and time-windowed events. See PvP and the Abyss for the PvP rules and reward structures.
Region Naming
AION 2's region names and map layout are not a 1:1 carry-over from the original Aion. Some IP-anchor names appear in the new world (Atreia, Elysea, Asmodae, Reshanta, the Abyss), but specific zones from the first game should not be assumed to exist in AION 2 unless verified in the live build.
