Answering first Val, The elf says "These filthy kobolds and their demon-king forced us to work their mangy farms - agriculture!" he spits at the last word. Farming, apparently, is not a proper elven endeavor.

To Cefos, another elf exclaims "Murder! Killing that kobold was justice. They deserved far worse than slow death for what they did to us!"

Xerxes elicits almost the opposite reaction than he was seeking. The elves are actually starting to get defiant. They are clearly afraid of you, but there's a look in their eyes that's daring you to strike out as fiercely as you can.

Then Sam casts his spell, and one of them says "Yeah, I'll tell you what you want to know."

You notice that the storm is once again weakening.
