Mossix Empire

The Mossix Empire was the longest lived empire in history and it dominated the entire Old World period. The Mossix was a civilization inhabited by the Inheritor Species and was renowned for its wealth, cultural achievements, theology and sheer size. For almost the entirety of its existence, the Mossix was ruled by Eternal-Emperor Etterhael.
The end of the Mossix during the First Coming of the End Times marked the end of the Old World and the end of the domination of the Inheritor Species.
