Azazel is a weapon...
For that his whole life has been nothing but to fight the demons of chaos in the name of the emperor of mankind no matter the cost.
Never to retreat,
Never to know fear,
Never to rest,
Never to Question.
This is the way of a primaris marine...
Long ago the all father sent the space wolves to go forth and bring justice to the thousand sons of magus the red, but during a mission to save a grand inquisitor from papa Nurgle something will happen that will change his life forever.
Never Azazel would find himself giving a quest to save a world from itself...

A great warrior of space and time becomes...a teacher?
