They are a Xenos race confined to 3 worlds in the Fidea system and mortal enemies of the Fidea Imperial Guard especially the 44th Fidea as such most of the information the Imperium has on this race came after the death of the commander for whom the species is named in 723 M41.(the name by which they call themselves is unprouncable) Once confined to the frozen world of Fidea Secundus they began a nascent space program sometime in M31 to escape only to discover that the worlds of Fidea III and IV were just as uninhabitable.
