Also, by Harpist all of the main characters are seriously overpowered. I mean, Morgon and Raederle aren't overpowered in comparison to their opponents, but they're well past the point of 'human', and human concerns don't matter to them as much as they used to.

That's, I think, a necessary part of Morgon and Raederle's narrative arc, because (ROT13 (http://edoceo.com/utilitas/rot13): gurl'er rssrpgviryl orpbzvat tbqf gb ercynpr gur Uvtu Bar), but it still cuts out a good deal of the hilarious family drama.
