The concept here is the enemy has won, at a least a major victory, if not a decisive one.  A major heroine (either main character or strong secondary character, depending on the story) has now been captured or surrendered and depending on the character the enemy has made her his wife, concubine, or personal slave.  These stories will possibly start with the ceremony/ritual making her into such and then focus on the aftermath.

These are stories ultimately about a man and a woman, though there may be minor side characters too.  Sometimes ‘love’ stories, sometimes not.  Some of the men will simply want to break the will/spirit of their prizes.  Others seek a genuine conversion, to make her love him, a true partner and happy to be his wife and eventually mother of his children.

The title is a little simplified.  These couples were enemies prior to the start of the story.  Sometimes you could describe the men as evil, other times they may simply be from another faction/country/world that fought their own.  They may or may not be human.  Again, the women will in fact be brides, sometimes not.  Separate from the question of love, sometimes the goal will simply be to make the woman loyal to something she had previously fought, sometimes it will be a journey towards actual evil, convincing her to commit cruelty with at least ease and perhaps even enjoyment.  Obviously at least some of these could turn rather dark, though it isn’t a requirement.

For the most part the couples should originate from the same source.  If the source is too heavily imbalanced gender-wise, there are a few options:  Possibly bringing someone over from another source that fits well or possibly gender-changing a character.

This is an adult group and there will be a lot of focus on that aspect of the relationships.  Also a lot of focus on the forced relationship and sometimes the woman gradually falling in love and embracing her husband’s philosophy and agenda and helping him fulfill it.  All members must be at least 18 years old.
