Human Coastal Raiders

"Princess Celestia, Princess Luna! I've got news from the eastern coast!"
>You look around the conference room filled with the princesses' most trusted advisors, all of their eyes on you
>"Yes my little pony? I hope it's important, I'm quite busy as you can see."
"Raiders from the north, tall and bipedal like nothing we've seen before. They've been attacking coastal cities for nearly a month, raping and pillaging wherever they please."
>Luna stands from her seat in indignation
>"To assault our lands and rape our stallions, these mares have neither shame nor morals! We shall mobilize-"
"Colts, Princess. They're colts as far as we can tell."
>Once again everypony in the room looks at you until Celestia speaks up
>"What do you mean colts? As in their raiding parties are comprised of colts."
>You reach into your saddlebag and hand over a written report
"In their entirety ma'am, they've also only taken mare prisoners. We'd assume they were after slaves if they weren't seen… 'going at it'."
>Both princesses crowd around the documents and many of the attached pictures
>You see them turn the page and gasp in surprise
>"Oh my…"
>They've seen photographs of their crimes if you had to guess
>"Rowing ships? They're woefully out dated, even by my standards, but that t'would explain the need for slaves."
"Not at all ma'am, you can see they row above deck, the slaves were taken bound with rope rather than put to work."
>Luna looks up to you
>"They must be very... Muscular, have you mayhap seen them yourself?"
"Yes ma'am, I was among the first pegasi to respond, we were about to give chase when they fled to their ships and sailed away."
>"How tall are they? Were there any mares among them at all?"
>You look between the two questioning princesses as sweat forms on your brow
>What kind of questions are these?

"I couldn't see any mares at all, and I suppose most of them are around your height princess."
>Luna and Celestia share a look before the latter decides to say something
>"Tall, muscular, savage colts who have dominated the local garrisons and more, they certainly are interesting aren't they?"
>"Most definitely sister, shall I send diplomats so that we may…" You just barely catch her licking her lips hungrily, "parlay with them."
>Both of them walk out, intent on dealing with this threat no doubt
"Princess Celestia, I need to have copies made of the documents."
>"Oh, yes, silly me. Here you go; Equestria thanks you for your service."
>You salute and flip through the report one more time to double check everything
>Oh buck, you must've dropped some of the pictures on the flight in
>"I call the dibs on that one!"
>"Fine, but I want the diplomat when he arrives."
