Necronis the Unmaker is coming. He is clawing open the Wall of Fire and influencing the entire Immaterium. Thousands of celestials have formed a barrier in front of him, but despite their combined wills the Dark God will soon rip the hole large enough to step through.

When he breaks free, he will tear the universe apart.

He is gaining followers and a large group of Necronites have set up camp in front of Appleton's Old Cider Factory, preparing to welcome their evil master with open arms.

Just when everyone is at a complete loss at how to combat him a mysterious stranger appears at the Nocturnal Academy who just might have a solution.

Unfortunately Rhys Kelly has lost parts of his memory and has no idea how he arrived at the school. Before he can help to combat Necronis he needs to rediscover exactly what he can do. It is up to the teachers, and Alice and her friends, to shape this middle-aged computer programmer into a lean, mean fighting machine.

But not everyone believes Rhys to be the answer to their prayers and Professor Abbacus even sees him as a threat.

And to make matters worse, the delinquents at the Old Cider Factory have gained some powerful new leaders and are planning a bloody takeover of their own.
