"They're many names given to the things of this vast consciousness that we don't understand, are afraid of, or otherwise just don't want to be associated with. These creatures, though familiar in appearance to many common races, have no name for themselves, but have been appropriately named "Concordare Iram", Translated: Harmonized Rage."
A race that are always born as twins and only one recieves a soul. The other is soulless therefore without pity, shame, or guilt. The evil race. Can't tell them apart by looking at them.
