That's looking pretty solid, felicitousArtisan. We are in business.
We don't know that the Dersites weren't actually present, but on the other hand, we don't actually know if they weren't present either. So I used creative license and added them to the storyboard to fill out the first part of the battle. Partially for rule of cool, partially because it lets some trolls get a bit of pre-battle spotlight, partially because I think it actually is a good question about where the Derse soldiers would be in a battle with the Black King.
