   Summary

   He doesn’t belong here... A twenty-first-century guy stuck in the body of the Great Angel feels like an imposter. What does it matter if his favourite movies are now lost media and an unfamiliar thirst for blood gnaws at him?

   Sanguinius, also known as Guin isn’t some hapless bird crashing into a window, but an angel shattering through stained glass into the 30th millennium.
