One nice thing about making this song about Dorial is that seems like it'd be much harder for our detractors among the Asur to try to minimize Dorial's accomplishment compared to if it had been about us. Sure, Dorial gets some blowback just from being associated with us, but it still seems that it'd be less difficult for them to dump on the criminal exile that got 745 elves killed compared to the innocent blade lord who's only crime is accompanying said exile given the magnitude of the accomplishment he managed.
