The Horus Heresy, but I’m a Loyalist

(Ensemble cast, no female lead. The author is a longtime Warhammer fan, so don't expect wildly out-of-character plotlines. The protagonist is transported into the 30K era as a Primarch.)

What happens when a Warhammer-loving gamer actually ends up in the Warhammer universe?

Lorgar: "Come on, man! Of all the people you could've made me, you made me Lorgar?!"

No system. No way back. As the Primarch fated to be corrupted first, how can he turn things around?

By killing Kor Phaeron and Erebus first, of course!

Lorgar will unite his Legion's homeworld and launch a glorious crusade beneath the Emperor's light. Let xenos and heretics tremble before the wrath of the Word Bearers! Let the stars fall! Let the flames rise! Let the Warp burn!

We bear the Emperor's word! We shall strike down the enemies of mankind!
