ahh, basically the idea would be her lover from when she was just a squishy human. she was once married to a merchant she didn't love. while she was married, she ended up falling in love with a guy and he felt the same about her. she got preggers and he left to go fight some war or battle and never came back. so she had the kid and his kid basically lived on.
i was thinking that her lover became a dragonborn so it would make sense that he never came back? like it would be interesting to have them connected telepathically but have not idea the other is that person? if that makes sense. like they'd be like "oh, that name is really familiar but that can't be them." yada yada.
if not, that's okay too! we can swing something else. no biggie!
