"I make things, mostly." Some of the other people he's met can do much the same, although they have limitations he doesn't. The train Nico has now is, of course, a mildly impossible object. The sort of thing that doesn't exist outside of dreams. "Can't make large objects here, though. Too far from ley lines for that."

Ley lines are, at least in Ronan's experience, something that anyone knows about. Gansey - before Gansey also became a forest and not a person - was as normal as a person could be while still being heavily obsessed with dead Welsh kings and he knew more about ley lines than the people Ronan knew who actually used them. Same with Gansey's weird professor friend.

Forests made of power, of energy, though? That's information to keep to yourself. Only the Greywaren would have need of such a place anyway - or another dreamer, and Ronan was pretty sure there wasn't another one of those on the train.

"Trinkets like that are easier for me here."
