Sometimes the plot ideas flow easily, but I'm feeling uninspired tonight. But maybe you creative people have some awesome ideas!

This is for a table top campaign, so some things are already set. There is only 1 PC. He's a first level fighter.

Setting: Medieval fantasy along the lines of D&D. Magic is around, but relatively rare. The PC is headed to a mining village, hoping to find an engineer to help him drain an underground pool. (Believing there is treasure there. That was the last episode of our game.)

So I've got a vague idea of maybe a cave in in the mines. Either the engineer is engaged trying to save trapped miners. Or maybe he's trapped himself. There are kobolds around to complicate matters. Could somebody in the village be in cahoots with the kobolds? What are they after?

Brainstorm ideas welcome! And if we come up with something that could turn into a play by post game here, bonus!

Maybe the kobolds also believe there is treasure in the pool, and they get to the engineer first. Or maybe the engineer has family who is in danger, and the PC needs to help them to get his help. Idk what the PC is like, but if he's the reluctant hero type, this could spawn some nice character development.

He's a first level fighter and he's alone. Unless he gathers some allies for anything geared toward his level, the only character development he's going to get is a casket.

Yeah, I definitely need to give him the opportunity to recruit some help from the miners or other townsfolk if there's going to be any combat involved (which I'd like there to be some).

Hmmm... I kind of like the idea of the engineer's family being in trouble. The PC has a little bit of money, but if the engineer owes him a favor, it would save his meager funds.
