Erātus is a mistake, one that should not exist. Long ago, the times gods of each pantheon clashed in epic combat, each attempting to weave the threads of time in their favor in order to gain the upper hand. This battle would threaten to unravel the fabric of time itself, until the one pantheon without their own combatant thus stepped in, the mighty Izanagi, for lack of a true god of time, would step in and grab hold of catastrophic anomaly that was forming from such grand combat. While the others continued their clash, Izanagi would capture each new mistake in the timeline and confine it to a single point. After the battle, that point would remain in Izanagis possession for an age as it attempted to stabalize itself as he could not unravel and dismiss it himself. He would ensure that the captured threads would not unravel until the day that such a strand could be given form by the Japanese god. Seeing as he possesed no true god of time amidst his ranks, he would shape that point into a creature of its own. A frail, yet intelligent figure, Erātus would be born. A mistake in time, one that shouldn't exist in the first place, Erātus would be given a task to prove his worth, to become a part of the pantheon. The various timelines that clashed together in order to make his very fabric of existence had granted him eons of knowledge before he was even born, some such information even stemming from times yet to come, though he may struggle to recall such information in his current state. He would be tasked by Izanagi to test his abilities and refine them so that he may one day prove his worth, though the grieving gods goal would be far from altruistic. Izanagi had been given the chance to be given one who could turn back time itself, and perhaps, he could be given back his lover. This situation proved beneficial on all fronts for the fallen god. Either he receives a keeper of time into his pantheon, and is granted back that which time once took from him, or the strands that make up Erātus would unravel when he fell, ridding the world of such a mistake. As for what path was truly taken though? That was for Erātus to yet see along the threads of time.
The riddle of time is one of the oldest mysteries of all creation, all the more tragic since its near destruction. The shattered pieces fade in and out providing power to those that know how to capture it.
