The Rashan were are speculated to have been created by the [[Old Ones]] during the [[War in Heaven (Necron)|War in Heaven]]. At this point, the [[C'tan]] had allied themselves with the [[Necron]]s against the Old Ones, and had beseiged their last bastions. In desperation, the Old Ones manipulated life into new forms with an ever stronger link to the [[Warp]] as potential warrior races with the ability to channel [[psychic]] power to defend themselves. This is speculated to have included the Rashan, along with the [[Eldar]], the [[K'nib]], and many others.{{Fn|1}}
