Akasch
The Akasch are one of the three higher races created by the Mother Goddess Thiol at the beginning of Erenor's history. Unlike the Ipnya and the Nuon, the Akasch turned against the natural order and became one of the most dangerous threats to the world. They are currently sealed in another dimension, though their influence continues to leak through.
Physical description
The Akasch are serpentine beings, roughly two to three times the size of a human. They are intelligent, powerful, and inherently hostile to the other races of Erenor. Their physical form distinguishes them from the humanoid Ipnya and Nuon.

Nachashgar
The Akasch built their own city, Nachashgar, which served as the seat of their civilization. The city's exact location is debated in the lore, but it existed in the dimensional space that the Akasch now occupy in their sealed state. Nachashgar represents the Akasch's capacity for organized civilization, making them a more complex threat than mere monsters.
The seal at Aegis Island
The Ipnya, the magically gifted higher race, managed to seal the Akasch in another dimension. Aegis Island is a key location associated with this seal. The barrier between dimensions is not perfect, and Akasch influence seeps through at various points across Erenor, corrupting wildlife and creating dangerous anomalies.

Connection to Anthalon
The Akasch and Anthalon's Crimson Army both exist in sealed dimensions, and both seek to return to the physical world. Whether the two forces are allied, competing, or unaware of each other varies depending on the era of the lore. Both represent existential threats that motivated the creation of the Chosen, mortals who guard the dimensional gates.
In the original ArcheAge
Akasch-related content appeared in the original game through corrupted zones, dimensional rifts, and story quests that explored the nature of the seal. The threat of the Akasch breaking free served as a background tension throughout the game's narrative.
