Watch Ponies

Magicians, or what you could call them, roam around cities. What do they do, you ask? They hack.

Aiden, a modern magician, hunts for the name of a pony who sent a pony after him. He changed his way of life because his neice is dead at the age of six. As Aiden struggles to keep up with parts of his family, he pursues the stallion who sent a killer after him.
