Less than a day later, there was a gathering of the monsters to the palace. Asgore stood before them. All the souls of the humans floated in his hands. Despite the cheers, he could look at none of his subjects. This was his doing. The regret couldn't be undone. He couldn't turn back now.
Asgore held the souls close as he addressed his people. Undyne would lead the armies.. They were going to wipe out the humans.. And everyone cheered. A few were half-hearted, but soon were fully there. One human couldn't stand for the many and that soul was in their rulers hands.
A blinding light came from the top of the stairs where Asgore stood. It lasted for only a moment before standing before the monsters in a golden light was their king. The King under the Mountain, stood tall, wide golden wings spread from his back and his armor looked even more gallant than before. Despite the new power, he still wouldn't look directly at anyone and had to look away when he saw Toriel standing in the back.
The King's eyes glowed bright like galaxies as he turned, trident in hand, towards the barrier. He gripped the red hilt tightly before surging forward. The ground shook as he rammed into the barrier. Cracks ran up the manifested energy like glass before shattering and slowly disintigrating into dust as the pieces fell. Asgore stood there, shoulders rising and falling slowly.
Undyne walked up to her king and placed a hand on his arm. Asgore looked down at her and nodded. She would gather the monsters and group them where their abilities could be used best.
He'd been the kind king once. Someone that greeted everyone with open arms. Now Asgore felt hollow as he looked out into the open world ahead. He'd take it all back. He would renounce this path if he could... But it was too late. The time of the humans was nigh. It was time for the rise of his people.
