The One Where Horus Loses It

Title: The One Where Horus Loses It

Intro music plays, with a voiceover reminiscent of Ron Howard's narrations in Arrested Development. The scene opens on Terra, with the Emperor standing at the top of his Golden Throne, gazing out at the galaxy.

Narrator: This is the Emperor. He had it all — a thriving galaxy, a fleet of loyal sons, and the promise of eternal rule. But his favorite son, Horus, was about to ruin everything.

Cut to Horus, standing brooding on his flagship, the Vengeful Spirit.

Narrator: And this is Horus. He was about to make a huge mistake.

Flashback to Horus being appointed Warmaster. The Emperor pats him on the shoulder.

The Emperor: You’ll do fine, Horus. Just don’t get corrupted by Chaos, okay?

Horus: (laughing) Me? Corrupted? Come on, Dad.

Narrator: But Horus was corrupted by Chaos.

Cut to Horus on Davin, lying on a bed with a Chaos-marked wound, sweating profusely. Enter Erebus, looking shifty.

Erebus: You know, Horus, if you just embrace the powers of Chaos, you could totally overthrow your dad and, you know, run the galaxy.

Narrator: Erebus was the guy you didn’t want your son hanging out with.

Horus: (confused) I dunno… my dad said I shouldn’t—

Erebus: Your dad? The guy who ditched you to build his weird webway project? Come on, Horus. Live a little.

Narrator: So Horus made a series of increasingly poor decisions.

Cut to Horus standing dramatically in front of his brothers, all dressed in dark, menacing armor.

Horus: I am your Warmaster! We will take the galaxy for ourselves, in the name of Chaos!

Fulgrim: (raising a glass) Finally! I thought we were never going to have any fun.

Narrator: Fulgrim was the one who took things too far, but we’ll get to that later.

The camera zooms in on Horus's confused expression.

Narrator: Horus didn’t really understand Chaos, but he was in too deep now. So he started a rebellion against his father... who was a little busy at the time.

Cut to the Emperor sitting in the Golden Throne Room, fiddling with the Webway Project.

The Emperor: (to Malcador) So, I’m thinking if we just reroute the Webway entrance through—

Malcador sighs, holding up a report.

Malcador: Sir… I don’t want to interrupt your very important project, but Horus just… you know… started a massive galactic rebellion?

The Emperor: (annoyed) Horus? He’s fine. He’s probably just upset that I didn’t take him on the Webway trip.

Narrator: The Emperor was terrible at reading his sons.

Cut back to the battlefield. Rogal Dorn is standing on Terra, arms crossed, looking overly serious as always.

Narrator: This is Rogal Dorn. He’s basically the responsible one, which meant he had to clean up everyone else’s messes.

Dorn is fortifying the defenses of Terra, arguing with Perturabo over vox.

Perturabo: (over the vox) You don’t understand, Dorn. I built better fortresses than you ever did.

Dorn: (sighing) Perturabo, this isn’t about you.

Narrator: It was always about Perturabo.

Cut to Perturabo angrily knocking over a pile of fortress models in his quarters.

Perturabo: Why does no one appreciate my siege warfare?!

Meanwhile, on the other side of the galaxy, Lorgar is having a moment of self-reflection.

Narrator: This is Lorgar. He was the reason everything started to go wrong in the first place, but nobody paid attention because, well… he’s Lorgar.

Lorgar is standing in front of a massive Chaos altar, looking smug.

Lorgar: It’s all going according to my plan. The galaxy will embrace the glory of Chaos!

Cut to the other Primarchs, who are visibly annoyed.

Magnus: (sarcastically) Oh, your plan? Sure, Lorgar, whatever you say.

Narrator: Magnus, of course, wasn’t really in a position to talk about poor decisions.

Flashback to Magnus shattering the Emperor’s Webway Project by using psychic powers to contact him.

Narrator: Magnus broke everything. But to be fair, he thought he was helping.

Cut to Magnus standing in the ruins of the Webway.

Magnus: (sheepish) Uh... Dad? I can fix this.

The Emperor: (furious) You’ve ruined everything!

Narrator: And now, Magnus was in big trouble.

Scene shifts to the Space Wolves invading Prospero. Russ is storming in, wrecking everything.

Narrator: Meanwhile, Leman Russ was loving it.

Leman Russ: (shouting) Burn it all down! Dad said it was okay!

Narrator: Except, of course, the Emperor didn’t actually say that. But Russ wasn’t one for reading the fine print.

Back to Horus, who is now trying to figure out how to get to Terra. He’s sitting at a war council with his chaotic brothers.

Horus: (frustrated) Okay, so how are we going to break through the defenses?

Fulgrim: (casually) I could just, you know, seduce them. That works on everyone.

Angron: (punching a wall) NO! WE BREAK THROUGH WITH FORCE! BLOOD FOR THE BLOOD GOD!

Narrator: This was Angron. He had… some issues.

Horus facepalms as Angron continues smashing things.

Horus: Okay, no blood gods for now. We’re going to Terra, and we’ll do this my way.

Cut to Terra. Rogal Dorn is still fortifying the walls. Guilliman arrives, looking calm and organized.

Narrator: And then there was Guilliman. He was the one who actually had everything figured out, but no one really wanted to hear about it.

Guilliman: (presenting a massive strategy map) Okay, so I’ve drafted up a plan to reorganize the Imperium after we stop Horus. It involves restructuring the Legion system into Chapters—

Dorn: Guilliman, we haven’t even fought Horus yet.

Guilliman: (calmly) I know. That’s why I’m planning ahead.

Narrator: Guilliman was very good at planning ahead.

Cut to Horus’s fleet finally arriving at Terra. Horus stands dramatically on the bridge.

Horus: (shouting) Begin the assault! The Throne will be mine!

Cut to Rogal Dorn standing on the walls of the Imperial Palace, unflinching as bombardments rain down.

Dorn: They’ll break before we do.

Cut to Perturabo, commanding the siege from the other side.

Perturabo: We’ll see about that, Dorn!

Narrator: It was the galaxy’s longest-running sibling rivalry.

The battle rages on. Cut to Sanguinius fighting Chaos forces, looking heroic and angelic.

Narrator: Sanguinius was doing what Sanguinius always did. Being awesome.

Sanguinius single-handedly takes down a Bloodthirster.

Narrator: But this was all leading up to one final showdown.

Cut to the Emperor boarding the Vengeful Spirit with a squad of Custodes.

Narrator: After Horus did some serious damage to Terra, the Emperor decided it was time to stop playing around.

Cut to Horus waiting on the Vengeful Spirit, pacing back and forth.

Horus: (grumbling) Dad’s gonna be so mad…

The Emperor arrives, sword in hand.

The Emperor: (stern) Horus, this ends now.

Narrator: It did not end now.

Cut to Horus and the Emperor battling in a dramatic, over-the-top fight sequence. Sanguinius is lying on the floor, having sacrificed himself earlier.

Narrator: Horus killed Sanguinius. Which was a real bummer for everyone.

The Emperor strikes Horus down, delivering the final blow. Horus collapses.

Narrator: And that was the end of Horus.

Cut to the aftermath. The Emperor is back on Terra, critically injured, being placed on the Golden Throne.

Narrator: But it wasn’t exactly a happy ending.

Guilliman stands next to the Emperor, looking at the ruined state of the Imperium.

Guilliman: (sighing) Well, I guess I’ll just... clean this all up.

Narrator: And so, with Horus defeated, Guilliman began his slow takeover of everything,

while the Emperor was stuck on a very uncomfortable chair for all eternity. It wasn’t the ending anyone really expected, but it’s the one they got.

Cue upbeat music as the screen fades to black.

Narrator: And that’s the story of how Horus lost it all... and the galaxy became a dysfunctional mess.
