Regular

At the end of the cavern, the ground sloped up, and had been made treacherous by the dripping water. It fought back, but the axe helped. One problem at a time. Climb hill! Read book!
And then the screaming started. His son, screaming.
It filled his mind.
They will burn
A staircase floated in his vision, reaching endlessly upwards into darkness. The screaming came from up there.
Feet slithered. The axe bit into the milky stone. Weeping and cursing, sliding at every step, Vimes struggled to the top of the slope.
A new, huge cave spread out below. It was busy with dwarfs. It looked like a mine.
There were four of them, only a few feet away from Vimes, whose vision was full of rocking lambs. They stared at this sudden, bloody, swaying apparition, which was dreamily waving a sword in one hand and an axe in the other.
They had axes, too. But the thing glared at them and asked:
“Where’s… My… Cow?”
