I've had an idea cooking for years about a harem plot. Where a war hero (my character) is rewarded with land and a peerage and suddenly sees himself being pestered by other noble families looking to feel him out/tie him to their own political factions or respective families. The idea being because politics is politics, and nobles having multiple wives and/or one wife and multiple legal concubines isn't unusual. If anything the reverse is considered abnormal. Limiting oneself to single spouse makes little political sense, particularly when it comes to the idea of siring the next generation. So his concubines would be daughters of more established families. Promised to him willingly of their own accord or unwillingly thrown at him by their families in the hopes of seducing him, bearing his child and becoming his official wife. Which would be a coveted position more important than a mere concubine.

The bulk of the idea would be about politics more than sex, raising a new noble house from the ground up. Making alliances and enemies and the new lord relying on his new concubines from more established families to help him do all these things he's never had to do before. Possibly some rivalry and competition between the concubines as their all essentially trying to seduce him/become his official wife and secure his power for the sake of their own families.

Of course not all concubines need to be from nobility. There could be 'lesser' concubines  and informal mistresses from more humble backgrounds. Other knightly families, military adjutants, or simply maids and servants that caught the lord's eye. How would these woman clash with their more highborn (and legally prioritized) 'sisters'?

I've never been sure how to write out that ideal effectively, without it just coming off as 'Looking for someone to play as my character's many lovers'. I'm also aware that this is often a tough sell for an idea. Asking a partner to play a harem. Which is why I am happy to take on the lions share of side characters and whatnot to balance things out. I'm also open to this being a small ground thing perhaps. Not just a 1x1 but a three way story perhaps to help split the character load out. 

The setting itself would be freeform. Something we make up. The 'empire' could be entirely composed of a single race, human or otherwise. With only one species dominating and colonizing the stars, or be something more multi racial. I do see this as something sci-fi though i'm not necessarily bound to that. A good steampunk/fantasy/what-have-you pitch is welcome. But I've always love the idea of mixing high technology and spaceflight with neo-feudalism and aristocracy. It makes for such a fun and interesting combination. It's probably why I love Battletech so much :P 

Anyway. I don't expect much nibbling on this as like I said, I know it's a tough sell at the best of times. Still. I recently had caused to be reminded of this old idea and figured it was time to try and pitch it. By all means hit me up if it interests you. Or you simply want to help me brainstorm and flesh out the concept without committing to the game.
