"Um, hello. This is Scootaloo. I'm recording this message for you... Well... Dunno, maybe you ain't gonna listen to it...

"Anyway, you are the first Overpony of Rapture Hydrostable. As you may know, we've already built some subterranean Stables in Equestria, but yours is something completely different. I think you already noticed, he-he-he... Oh... I'm really sick of this shit, Overpony. There's a war knocking on our door and all I do is sit in my chair with a bottle of Wild Pegasus and record these Luna-damn messages. I'm so damn useful, yes?

"Anyhow, besides just being the only submarine Stable, yours has a purpose. Do. Better.

"Those Princesses got us in the fucking war. Those Ministry Mares gave us means to kill thousands of innocents. Those zebras excuse murder with their religious bullshit. Well, fear no more, Rapture Hydrostable, for you will be far away from the megaspells when they fall. And after they fall... Live like you've never lived on the surface.

"Coal mining and gem embargo broke our relations with zebras. Stable-Tec orders you to praise the free trade. Scientists under MAS and MoP gave us the megaspells. Stable-Tec orders you to praise the free will of art and science not being employed by any slut in tuxedo. Princesses and Ministries strained and enslaved the ponykind. Stable-Tec gives you a Stable free of this shit. Do whatever you want, just remember. No government. No slaves. No Ministries. No gender and race discrimination. No censorship. No fucking taxes. Just ponies and zebras (yeah!) living in peace, harmony and happiness.

"And yeah, your Stable starts its work immediately. We are yet to build some Stables on the surface, but heck, you should totally start now. We gave you some room and food, some raw materials and shit, but it's up to you to build... Well, whatever you actually want. Who am I to tell you where to expand, right? You're the boss now.

"Welcome aboard, Overpony. Fuck, I need a drink..."
