“Thelgen Rock over yonder is something of a natural wonder. It's the only known source of incendicite in the world!
The stuff's rare, highly sought, and ridiculously explosive. Hit it with a steel mining pick and you'll set off a fireworks show that'll put a room full of goblins to shame.
Luckily, I've developed a spark-proof pick for such tasks. I'll loan it to you if you bring me back some incendicite ore, and I'll split you in on the profits, of course.”
