The Snowthorn Pack

A gnoll pack dens in a played-out Snowthorn shaft. The shaft boss wants it cleared.

Requirements

Meet the shaft boss at Snowthorn Bank
He has a tooth on the counter the size of his thumb. 'Gnolls in the old number-three shaft. Pulled it last night from a timber. New dig starts in three days. Clear them.'
Check the played-out vein for sign
Scat and bones in the entry chamber. The pack is using the old vein as a larder. They've been working it for at least a month. They're settled, which means they'll fight.
Bottle them in the shaft entry
You drop two of the rotten props at the entry chamber to bottle the chamber and force a single approach. The pack hears the timbers fall and moves toward the noise. Good.
Take the pack leader
The bottleneck held. The leader hit the choke first and hardest, with the rest of the pack stacked behind it. You took them one at a time as they pushed through. They won't be back this winter.
Burn the den scraps at the surface
You haul the worst of the larder out to the snow plot and burn it on a downwind fire. The smell carries west, away from the new dig. The shaft is breathable again by evening.
Settle with the shaft boss
He pays in coin and a sack of fresh-cut ore from the new dig's test holes. 'The crew starts in three days. You bought us a clean shaft. Don't be a stranger.'
