Ray Ibn-La'Ahad somehow gets trapped in a war between two parties called Atlas and Sentinels. Without an exo-suit to work with, how will he survive with the Assassin skills and weapons to survive? As a pony, will he still survive? Can he adapt to these new conditions? What will he fight for? How many is he going to lose?

(Side Note: I'd recommend you read The Assassin's Creed before you read this just to get a feel of the characters or what I mean by 'may kill him once again' in the short description. Most likely you won't understand the beginning if you don't read the first story.)
