A thought after playing with Riot in an RP with a friend of mine.

NOTE: I did use some MLP characters in this roleplay/story but only for a bit and as cameos. I did not do anything according to what happened in the episode, i made my own storyline from it.

Explaining that the draconiqui all disappeared by the guardians of order who's mission was to seal away or destroy any source or cause of chaos. When Discord caused chaos the leader of the order named Pareo, fought him, his sisters Celestia and Luna turning him to stone since the two brothers could not destroy each other.

After Discord was sealed away, he made it his own quest to hunt down every last Draconiquus. Unfortunately they are not easily killed by his guardians because of their many varied abilities so he resorted to sealing them away in a prison in his realm of order or in many parts of the universe when his prison filled.

Riot was caught in his eyesight and she tried to run away but he caught up to her and sealed her away within the dark void of space where she would bring no chaos. Proof of this are bright stars forming a constellation.

Now she remains sealed away going mad at the fact that she could not cause chaos where she now resides. In the realm of order one at a time a draconiquus is killed every few decades on account of how difficult it is.
