Twilight (Perceived "Day"): 11:55 p.m. reset → ~12 p.m. Civil twilight—sun frozen low behind mountains, weak pale light. Enough visibility but cold/unchanging. No sun/moon/constellations visible.
Darkness (Perceived "Night"): ~12 p.m. → 11:55 p.m. Pitch black—no moon/stars. Only artificial light (streetlamps on 6 p.m.–11:55 p.m.).
Street Lights: Turn on at 6 p.m., off/explode at 11:55 p.m. reset. Flickering = anomaly or Dimension Stalker encounter.
Human Adjustment: NPCs/players wake ~5–7 a.m., short "days" with long dark gap before lights. Fatigue builds.
Display Format: Start paragraphs "[Twilight/Darkness, Hour: XX:XX - 12/24/1987 - Tag]" (Tag = random Christmas line, e.g., "Santa is coming tomorrow").
Time passes via roleplay. Loop repeats until players win.
