The Spirit Wars were an interconnected series of massed conflicts between the Xi’an Empire and the Kr’thak, spanning multiple centuries (II.961 - II.1735; SEY 351 - 1342 ). These wars had a profound effect on Xi’an society; during a Kr’thak incursion in II.1706 (SEY 1305), Emperor Iith se Xy.ō and all in her House were exterminated. The Second Imperial age came to an abrupt end and a century of anarchy rose in its place.
