Sin’niroiha (“First Among Peoples” in Ihrimsû), was the King of the Nonman Mansion of Nihrimsul. The power of High Mansion of Siöl waxed and Nihrimsul was subdued by Cû’jara-Cinmoi. Sin’niroiha was forced to wash the sword of the High King of Siöl. After the Battle of Pir Pahal, emboldened by Siöl’s distraction, Nihrimsul and Cil-Aujas had revolted.
