This book is also known as "Come to Hogwarts to Learn to Slay Gods" and "Chainsword + Boltgun: Times Have Changed, Wizard Master!"

In the dark 41st millennium, Bourne faced the Primarch Angron, who had ascended to the devil, in the Warp and was hit head-on by the Spinebreaker.

But his soul was neither polluted and assimilated by the Warp, nor did he return to the Golden Throne.

Bourne came to the world of Harry Potter.

ps: The content of this book is also friendly to readers who don't know Warhammer and Harry Potter. You can rest assured that the protagonist will not be tragic.
