Well, craft did it with his little shaman fucker. And this isn't divine intervention. This is just a "dream".
It makes even less sense if it's just a dream. Kind of a big coincidence, don't you think? The Loke-Khan suddenly has a dream about the recipe of gunpowder, and invents the musket. GG.
That's different. You'd need a shit ton of stuff for that. This is just going off to find something. Plus if the DM did that, I can do it.
Plus this could just be made up completely. I'm not saying we're gonna find it, just saying we're out to find something like it.
