At one time, a species of enormous humanoids inhabited Shoon. This world was situated in the Senex sector, found within the Mid Rim's Senex-Juvex area. These beings constructed various buildings and other structures all over their homeworld's landscape. By the year 43 ABY, this humanoid race had died out, leaving only the remnants of their constructions to indicate that they had ever existed. Just like the other planets in the Senex-Juvex, Shoon later fell under the dominion of the Ancient Houses, the Humanocentric and aristocratic families of the region. These families had settled the Senex-Juvex area between 1000 BBY and 700 BBY and had also enslaved the local alien inhabitants.
Daniel Wallace and Jason Fry introduced this species in their 2009 reference work, The Essential Atlas.
