At some point in her lonesome walk, the stone bricks has shifted into smooth reddish stone. Callahan payed it no mind

The dungeons didn’t obey the laws of the world above, they only obeyed their own rules. Callahan liked it that way. She only obeyed her own rules.

The stone blocks of the walls faded away, replaced by enormous boulders, the regular shape of the halls shifting into something more like a crack in the earth. Callahan had seen much of this underworld, but this was new. It was older, ancient and creaking. There must be something worth finding down this way.

The typical ember-pots of the more traversed halls had been replaced with torches, stabbed into the crevices like branches. She stayed back, the open flame was much more threatening than the low embers. She was much too deep beneath the ground to treat a burn. 

She turned a corner and the tunnel opened up on a huge space of old stone and open firelight. Small dishes of an inedible substance lay near the far wall. It was this that struck Callahan still as the stone she walked on.

The wall was cast in flickering torchlight, its creviced surface streaked with umber and clay. The shapes of horses, thin legged and racing across the stone. They looked like no courser she ever seen, they did not have the strength of build, the spark of intelligence in their dotted eyes.

There were strange prints as well, a square with five points. She had nothing to compare it to, and dismissed them. The paintings of horses were much more interesting.

Where did they come from? Probably the dungeon itself, a memory of every horse lost down here. How curious. Callahan had seen many things these dungeons had made, but this one was hauntingly beautiful, like the silhouette of a distant dream cast on the wall. Was it the dream of the dungeons?

Callahan turned back the way she came. As beautiful as the painting was, it was not a treasure she could take home, and thus worthless. What was she to do with it? Sit and stare? No, she’d need treasure she could carry. And this wasn’t that.
