Maybe Adelbern was banging someone after the Charr invaded or something, LoL.
But Adelbern isn't a true king, I thought everyone united under him because he was a great leader or something. So he wasn't actually royalty or nobility like Duke Barradin and such.
I'm assuming the ghost is referring to Ascalon, of course.
Also, do you think Salma in ToA becomes the queen?
