Asgore had thought they were dead, the seemingly faceless and voiceless soldier that had been fighting with them years ago. Those years had passed by rather quickly, the length of time taking its toll on the barrier's spell. One day, without any form of volition to do so, the spell had been pushed to far as the barrier broke. In the ten years it had stood strong, Asgore had gained three human souls from fallen children. Toriel had left and returned from the Ruins, still having regrets and grudges alike. But war was approaching, coming to swallow them whole. Those who knew to fight or had fought years ago brought out their armor and prepared for what they knew was to come. This war would be like a flame, one still burning, if not brighter from the gathered souls, that would both fuel the fights and be fueled by them in turn. The king was desperate for their best fighters, even asking upon the royal judge and old retired warriors. Out of hope, he sent out for the one they called Zenith. And they had answered. Trigger warnings so far: Mild swearing, insultation. (This list will get much longer) I give credit for inspiration to Undertale, the Time Before series, Royal Blue, and Cage of Bones, which I recommend you should go read.
