Both trolls are killed and hidden, drop what they held -- the large key among it -- the clearing gets its daytime description and is marked unvisited, and its picture's first two bytes -- the border and the attribute its canvas starts as -- go from night's black to day's cyan; the drawing itself is the same. Every new game puts the night back (NEW_GAME). Seen in the simulator: $00 $00 at the start, $05 $28 once day had dawned.
