"A massive dwarven city," Gavin whispered as he picked his way down the river bank, hopping from one stone to the next. "Imagine if you hollowed out a mountain, and lived inside of it. The sky replaced by rock, high high above, too dark to see where it ends. Below you, rock so hot that it's molten - churning and glowing as it lights the city above it. And the noise - Ellana, the noise! As if a hundred drums made of iron were slamming in your chest. You can feel it vibrate through your feet, right to the tips of your fingers."

He grinned.

"And a beard on nearly every man in sight."
