Tristan had always loved running and sports. When cancer had threatened his life, he had to give up his dream of being an Olympic runner. Tristan got hit by a car while saving a boy who fell in the street. Tristan was hospitalized and had two days to live. His last wish was to watch his favorite episode of MLP:FIM. He fell asleep and awoke in a colorful land full of ponies.

The list of characters are more but 5 is all I could add.
