Xeset

The magical city of Xeset was founded couple of years ago, when a powerful Magihail hit one of the floating islands of Archeon Islands. This magihail terraformed the land and the city that was there, changing it forever. It cannot be accessed by almost all creatures due to strange magical phenomena called the Grey Cloud that surrounds it, transforming anybody like they were touched by the magihail. Some speculate that you could still enter the place using magic but nobody yet tried. The only race that can access the city safely is the Aetherborn and this is their city. Numbering in the thousands or more, they live here, sharing their knowledge between themselves and send out units to gather more information about the world. This is also the place of the Eyes of Xandoroul, a secret organization among the Aetherborn that know the true origins of their race. However, Xandoroul is known. He is the "oldest" Aetherborn on Tethys, at least that's what is speculated as he lost almost all of his dust-like material that bound his body is now mainly magic. He is the wisest among them all and all knowledge is shared with him when an Aetherborn returns or a new one appears as Xeset welcomes all Aetherborn to the city.
