Long ago, you fell into MT Ebott, and was taken under the care of Toriel, who was the closest thing to a family to you
One day, Toriel came home with another human, who immediately set you with off feeling, they always had a dusty powder on their hands... And when they tried to leave Toriel attempted to stop them... And...
You watched it, and you ran after, ran for the heavens... And you tried to warn people, but nobody believed you, and couldn't stop them
You hid, where no one could find you, while The human and the Flower killed everyone, you hid at the barrier, you knew you stood no chance against them
You heard loud crashing in the judgement hall, it stopped, then Asgore speaking, then a high pitched voice pleading
And then... They were there, standing in front of you.. you were the last thing between them and the absolute, the soul containers appeared from the floor behind you
That filled you with Patience, Justice, Integrity, Perseverance, Bravery, Kindness... But mainly.... You're filled with.... DETERMINATION
