A rather strange and absentminded stallion has come out of nowhere, and broken into the royal castle. When he is easily apprehended for his crime of trespassing it is found that he is far more powerful than he first appears. It also seems he is even more impossible to contain. When finally he is found and confronted by the royal sisters he introduces himself as Chaos, and despite his name and power he seems to be a very calm and dignified stallion. That is until he reveals his origin, or rather, the origin of another, which leads to the immediate distrust of all.
Chaos insists that despite his past mistakes he intends to make good on his family's history, but Celestia "banishes" him to Ponyville. This way the wielders of the Elements of Harmony will be able to keep a close eye on him in case he's lying, but due to his dignified nature and relative charm Rarity comes comes to be close friends with him.
Will the trust of fair Rarity be enough to convince her friends of Chaos' innocence, or will this cause an irreparable rift between the closest of friends?
