After passing the third one, Ianto just had to ask.
“Jack, what’re those weird curly things?”
“You’ll have to be more specific, Ianto. Weird and curly is the order of the day around here,” Jack replied. He had a point; even the pale yellow grass was curly.
“The pink things like bent corkscrews sticking out of two mops twisted together.”
Comprehension dawned. “Oh, those things. They’re the equivalent of milestones, they tell people how far they are from the last village and how much further to the next one.”
“So how far…?”
Jack shrugged. “Didn’t say I could read them.”
