The Environmental Storytelling Pass
A fact your reader is told is a fact they can set down. A fact the room shows them is one they already believe. Take three things true about your world, and for each name the trace it leaves somewhere — something a visitor could see, hear, or smell without anyone explaining it. Three lines is the whole pass; it prints clean on letter paper.
Left is what is true. Right is what it left behind.
Write the fact plainly on the left — the kind of line that would sit in a lore document. Then, on the right, the evidence of it: a wear mark, a shortage, a habit, a thing built to prevent something. If the right-hand line could appear in the lore document, it is a restatement, not a trace.
Two examples, worked all the way through
read the right-hand column twiceNeither trace names the fact. Both would still be true if the lore document burned.
The tide-wells are metered by the Salt Guild, and the tide is not always generous.
Trace: every well-head carries a guild tally board, and the figures are freshly chalked — but the chalk is kept in a locked box, and the lock is new.
Iron quiets magic, so the old builders paid for a great deal of iron.
Trace: doorframes are banded three straps deep on the oldest houses, and around the newest doorways the plaster is blistered, as though something had tried the gap and given up.
The two ways a trace fails
Restatement — “the guild owns the wells” becoming “a sign saying the guild owns the wells”. That is the fact wearing a hat. Decoration — a detail that is atmospheric but implies nothing, so it survives the fact being deleted. A trace should be a consequence: something that is only there because the fact is.
