Open stone from one horizon to the other, and nowhere to put your back. The Plains teach endurance, which is a polite way of saying they remove everything that cannot last. Titan dragons lived here once, and what is left of one of them is still on the map, ribs standing out of the stone like a ruin somebody forgot to finish. That is where "forged by the wyrm" comes from. It was not a figure of speech to begin with.

Something lives inside what is left of it. The people of the Plains would rather you did not ask what it eats.
