Chaotic Heart, a killer for eighteen years as an assassin, finds himslf in a situation he never would have saw coming. It all started when he got arrested in Canterlot, and he gets a strange surprize at the offer given. It doesn't end well, and after that, he starts to find out exactly what his unique form of insanity means.

Crappy summary most likely, but if the story isn't better, tell me so please. Also, tell me later on if i need more tags because i'm not to good at guessing those things. Multiple other Charecters will be used as well, but i don't have the ability to put them all in.
