It's the 31st Millenium, and you wake up in the morning in you massive bed which you share with your girlfriend. You look next to you to see that she is not there and that her armour is left hanging on her wardrobe. You sigh, knowing exactly where she is. You hop off the bed and doing your morning ritual of eating breakfast, brushing your teeth, and putting on a fresh pair of clothes.
You then traverse your way through the massive Palace until you come to an elevator in her workshop. You input a secret code and the door opens, allowing you to step inside.
As you look at the button panel, there is only two buttons, a red one, and a grey one. You press the grey one and you start to go down...
Whils going down, you look out the window to the side of an elevator to what seems like am impossibly massive workshop, filled with rows upon rows of Imperator Titans, each one standing at least 500ft tall. There are a few other machines as well, such as Rhino Transports, or even Predator Tanks, but the Titans are the most impressive of all. You try to see the edge of the room, but it just seems like it goes on forever!
The elevator stops at the bottom and you step out. As you walk to the Schematics room, one of the main rooms of this massive underground complex, you see your girlfriend's sons in their Space Marine armour, accompanied by many high-regarding Techpriests. The give you nods of acknowledgement and get on with their work, constructing and repairing many different mechanical vehicles.
Eventually, you make it to the Schematics room, where your girlfriend, the overlooked Primach Perturabo, designing a new gun for the Imperator Titan. She is wearing steel-toed boots, a pair of Jeans, fingerless gloves and a black, tank-top. A bit unbecoming of a Primarch, but you didn't really care about that.
Hearing you walk in, she turned to you, seeming unamused and a bit grumpy.
"Hmph... Hello, my little Trinket... You shouldn't be down here..." She said, turning back to her schematic.
