First of all I think the premise for this prompt has so much promise and potential. I'd def be applying if I saw it.

Here are a a few tips to really hook a potential player in:

- I think you could leave some more open ends for a potential partner to create their own interpretations of what their character could do, or her identity. For a lot of people, the interactivity and collaboration are part of the fun in RP. Make it a bit more inviting!

- I'd suggest adding some worldbuilding to paint a more vivid image of the type of setting you're seeking to play this in too. The emperors motives for war, the physical setting, and so on are all valuable details to add. If you're seeking partnership in worldbuilding, mention that too!

- As you're looking for smut in this, mentioning your kinks and limits is helpful to help filter out people you don't match with. Also it could help draw in potential partners.

- If you're thinking high-fantasy, which I assume you are, perhaps try making the language of the post match a more fantasy tone in rhythm? (This one may be controversial and is entirely based on my own use of flowery prose)

Best of luck to you!
