Warhammer: What Do You Mean I'm the Emperor's Cousin?

[Warhammer, Space Marines, Invincible, A Different Kind of Warhammer, Fourth Disaster, Necrons, Tyranid Pregnancy, The Emperor Marries Slaanesh, Regent Guilliman as a Little Girl, A Cast of Transmigrators.] Wait, what do you mean I’m the Emperor’s older cousin, and I’m even stronger than him? In the distant forty-first millennium, the galaxy is burning. That damned Abaddon has split the Imperium into the Imperium Nihilus and the Imperium Sanctus. And Si Yan, a relative of the mighty Emperor, has just returned from beyond the galaxy. What will he think when he sees this miserable state of humanity? Like this: So you’re the only one who gets to be a Warp god, huh! And you’re still asking if my little brother sits on a toilet? What, are you lovesick? Next comes the wonderful life of Si Yan, the Emperor’s cousin, as he helps him suppress the Webway, punish his nephew, and improve the lot of humanity! But how the hell does this old geezer have five million Ultramarines? And what’s with all the other Primarchs defecting? Wait, why is this Primarch a transmigrator too? So much for playing fair! Looks like I’ll have to summon some transmigrators! As for that thing still sitting on the toilet? Si Yan: “Go, go, go! Do you think I have time to save you? Can’t you see I’m saving my adorable nephew? Get lost!”
