“The stall itself seems to move a breath's width each time you blink; Lyralei will sometimes trade unusual currency (a fond memory, a song, a promise of a future favor, or a handful of moonpetals) in lieu of gp — she provides an informal exchange rate (one vivid memory ≈ 200 gp, one true-laugh ≈ 10 gp) but the Fair's rules vary by vendor. Items bought under the glow of the second moon sometimes 'sleep' for a day and behave unpredictably (minor illusions, faint giggling, or blossoming leaves) until they're acknowledged by their new owner. Lyralei enjoys bargaining with riddles and may offer small bargains to parties who tell an entertaining story or perform a short song; conversely, insulting a stall's trinket (or stealing) may result in a harmless but embarrassing curse until removed with a Lesser Restoration or a sincere apology performed at sunrise.”
