Fort Aieuda is populated by a splintered faction of the Izzil Demons; those who wanted to preserve the artifacts held inside the Elven fort, which was located on the same island as Fort Izzil, to the east.

Inside Fort Aieuda are multiple Elven artifacts, that much is not in question. However, the Aieuda Demons have refused to give any information on what they are.

The fort itself is a hexagonal tower, with 4-meter thick walls of stone and sandstone, making it incredibly difficult to break through.
