Dawn was a dangerous time for Peter Cue because it marked the transition from darkness to light, making him more visible and vulnerable to detection. As a traitor, he was likely to be pursued by authorities or rival factions, and the early morning hours offered limited cover for his escape. Additionally, the changing light could signify the arrival of search parties or guards, heightening the risk of capture. Thus, dawn represented both a literal and metaphorical point of exposure for him.
