"No."


"No?" Elios says, taken aback.


"I'm not joining you. He knows what you're planning. I'm not joining your death trap."


"So be it," he says, a sneer forming on his face. 


Elios steps forward, knocking on the metal door. The guards open, immediately raising their bolters. Elios waves his hand.


"You didn't see me here. The voice of Slaanesh calls you, and you're his now. Move aside, and tell no one I was her," Elios says, strolling forward, leaving without looking at you.


In the next few weeks, you're quickly proven right. Elios is first. When he's found, he's had his limps slowly sanded off, before being thrown in a pit with mutants who tore him apart. A "mysterious" assassin attempts to kill Elizabeth, but Durge fends her off, only for a "malfunction" to destroy him the next day, incinerating him in a single blast. Elizabeth is killed by one of the ship's macro-cannons, taking out the shuttle they were going on, because of a sensor malfunction identifying it as hostile.


With his threats to power gone, the assault on the Imperium is on. The first few worlds fall with ease, as they're unprepared for the level of firepower that Kyros is bringing to the table. Still, issues arise. You're reinforced by those recruited from the conquered realms as well as throngs of war-bands coming to join your invasion. Still, Kyros gets greedy. He attempts to take on a Forge World, a world literally covered with layers of factories, run by the cyborg-engineers that are part of the machine-worshipping cult known as the Mechnicus. Kyros' grand plans to have a Forge World producing endless war machines are ruined when the planet's orbital defenses take out much of your fleet, and in the ensuing battle the factories are leveled. When Kyros finally takes the planet, it's nothing but a smoking rock.


Everything falls apart after that. In a desperate attempt to capture geneseed stores to allow him to take over the home world of a Space Marine chapter known as the Horned Kings. The chapter is wiped out, but again Kyros gains nothing as the last act of the Chapter Master is to detonate their geneseed stores. 


At this point, Kyros' forces are a pale shadow of their previous selves. Cain and most of the Goliaths were taken out as their landing pods were wiped out in an attempt to take the Forge World, and the gladiators are wiped out by a suicidal charge by the Iron Kings. They're not the only ones gone. Fay is killed, along with many of the tribals, in the Genesee stores' destruction. It's only at that point that you truly stop caring. Your tribe is gone, only a few faces so grief-stricken you can barely recognize them remaining. You don't care if you reach Terra. You don't care if you live. You don't care if you die. You just don't care, about anything. 


You find yourself on some war-stricken world, killing. Scores of refugees are wiped out as your hand waves and warpfire spurts from the earth. Once, you would've have wanted to hurt innocents. You wouldn't have done it. Now, you feel nothing as you smell their cooked flesh. A Space Marine charges towards you, but you stare at him. The Space Marine screams as you force him to tear his own arms off, tossing them aside and having tentacles rapidly grow out of his arm sockets, before his mind is corrupted and he charges, roaring towards his allies as he begins to tear them apart. You  watch as a Dreadnought's legs buckle under your telekinesis, sending it toppling and tumbling down before it explodes. You levitate a Guardsman into the air as he howls in terror, be...


The earth shutters as artillery booms, sending you into the air. Artillery tears through the earth, and you slam into an APC. You hastily stand, to see dozens of refugees piling out of the crippled APC. You see to your surprise Tribals shooting at you and the other refugees, bullets thudding into the metal next to you, before they're killed by bolter fire. You look at your reflection in the half-broken window of a destroyed building, and realize why they were firing. With your now torn clothes and dirt-covered face, you are now indistinguishable from the refugees you've been killing.


You hear a dozen monstrous roars from your allies off towards your right, signifying a charge, before it's answered by the shouts of the Imperial Guard and Space Marine preparing a counter-charge. You could try to escape this. Hide amongst the refugees. Find a way out of this life. But what would be the point? You hear the charge nearing. Damn Kyros, putting you in this situation. Maybe you should be the one to finish his mad invasion? Or maybe you should return to what you know, and fight?

You just walk into the battlefield and let it end

You stroll forward into the battlefield, watching as dozens of brightly colored and heavily armored Space Marines near you. They raise their weapons and fire, as others attempt to get to your with chainswords. You offer no resistance. You don't attempt to dodge the fire, or to block it, or even move. You feel the shells burst through, your organs being decimated. As you collapse back in a pool of blood, you hope death will give you the peace you could never get from sleep.
