Kozemar - Dying Light
Karamati first appeared as a wandering prophet, who had studied the signs and portents and warned of a great cataclysm to come. He gathered followers from all over the land and enjoined the heads of state to combine their resources into the building of the Great Crystal.
When the Great Crystal was activated, Karamati himself disappeared. Scouts dispatched to investigate the Crystal site found nothing but devastation and the blazing crystal, along with evidence of a massive battle involving powerful magic.
Karamati’s followers declared him to be a martyr, having stood against an assault by the powers of darkness and managing to activate the crystal even as he was destroyed. They lifted him up to sainthood and began calling themselves the Keepers of the Light, swearing to preserve his legacy and continue the defense against the darkness that be began.
