Horus
- Horus was weak, Horus was a fool. He had the galaxy in the palm of his hand, and let it slip away.
- -Abaddon Who Ironically is an even BIGGER failure than Horus and has no arms to hold something in his palm anyhow.
Horus or (who is sometimes named Lupercal, Horus Lupercal, Horus "Lupercal", or Horace) was the Primarch of the Luna Wolves/Sons of Horus/Black Legion, and the main figure in the event known as the Horus Heresy (this is NOT a dead giveaway. Oh no) in which he, yeah you guessed it, betrays his father of sorts - the Emperor and turns to Chaos... heretically. Before that, he was the Primarch most favored by the Em--oh come on! If you really need to be told any of this, what the fuck are you doing on /tg/ in the first place? Much like the Emperor being crippled and the Imperium devolving into a bureaucratic grimdark empire; The death of Horus and the placement of Abaddon as the most powerful Chaos champion evar turned the chaotic legions from a genocidal force bent on utter domination for the glory of Chaos, to a Saturday-morning cartoon villain organization...... well except for Angron and the World Eaters who get shit done now and again.
It is argued that Horus was not actually evil but was possessed by the chaos gods or that he believed that thee emperor wanted to be a god.
Long story short, the Imperium got fucked up because this guy had daddy issues. Because the Chaos Gods showed him horrific visions of the future, supposedly under the Emperor's rule. Lolirony. HORUS WILL LIVE AGAIN TERRA WILL FALL. oh shit! Shit will hit the fan. *BLAM* Heresy! YOU CAN'T SILENCE THE INEVITABLE TRUTH. *BLAM* Heresy!
