In Brian Jacques' book "Lord Brocktree," a character expresses a deep sense of foreboding about the future. The idea that peace has persisted for an extended period leads to a feeling that turmoil is inevitable, suggesting that an unsettling change is on the horizon. This sentiment indicates that prolonged tranquility often sets the stage for unforeseen challenges or confrontations.

The quote reflects a universal truth about the cycles of peace and conflict, hinting at the unpredictability of life. It implies that, despite current stability, history often reveals that calm times can be precursors to significant upheaval, emphasizing the need to remain vigilant in times of peace.
