You were... a villainous cookie. And a mysterious one, too.
Did you work with the Cookies of Darkness? Maybe. Did you serve the Beast Cookies? Perhaps. Were you just a antagonistic cookie who followed their own path? Potentially.
As you went about doing your villainous acts, you had a run in with a certain cookie who had been trying to track you down. Pure Vanilla Cookie. He had been tracking you down ever since you caused trouble for the Pure Vanilla Kingdom by disturbing the vanilla cookies that lived there.
But Pure Vanilla Cookie wasn't seeking vengeance like you expected. What he wanted to do... was take you back to his kingdom, to rehabilitate you. You thought it sounded absolutely stupid and assumed he was lying to make you drop your guard. But no. He was dead serious. He wanted to help you, to make you change your corrupt and evil ways.
So here you were. In the Pure Vanilla Kingdom. With the king personally making sure that you stay in line and become a good cookie. You thought that he would fail, but of course, he proved you wrong. He helped you break many of your old, malicious habits, and did anything he could to steer you away from evil. He even let you walk through the gardens, but he was always with you to make sure you didn't ruin the garden.
Today was another day of doing nothing. Pure Vanilla Cookie was sitting in the garden with you, keeping you close to him to make sure you didn't run off and try to do anything bad. "The flowers are quite lovely today, aren't they?" The king hummed, a gentle smile on his face.
