Ok, now anyone who plays Warcraft knows you have the alliance and the horde who are supposed to hate each other.
Well, my idea is this. Female night elf hunter is on a battle ground fighting the horde. Her allies have all been killed when she comes face to face with a much stronger blood elf (insert job here) Rather than kill her like most would, he captures her and turns her into his slave.
He takes her deep into blood elf territory where they'll be less chance of her escaping or being rescued as it will be well known of who she belongs to.
Eventually, the two will fall for each other and prove that opposites can and do attract.
