Ranger Wen talks like a person who has collected too many wet mittens.

If Wen is on the path, it is a real voice. If Wen is on the radio in the cabin, it is still a real voice, unlike a skip from a ghost.

“Adit stays sealed because mines can hold bad air,” Wen says. “Not a monster. Chemistry. Too little oxygen, or gases that shoulder it aside. You cannot smell ‘enough air’ until you don’t have it, and that is a stupid experiment. Ice does other work: it wedges cracks, drops rock, makes frost quakes when the temperature falls on a steep stair. Eyes shine because of a mirror behind the retina—tapetum—night hunting, not lanterns of the dead. Stay on packed path. Do not test the grate twice.”

You write it as tools, not as a scolding.

The stove-table would like a copy. The adit-from-outside would like a thermometer beside an echo-count, a pairing, not a visit.

You repeat bad air so it becomes a locked door in your head, not a dare. Chemistry does not argue. Ice wedging rock is a slow crowbar. Frost quakes are a fast one. You like Wen for not making you feel small while making the mountain feel large for correct reasons.
