Act as a seasoned speculative fiction writer with a knack for surreal world-building. Craft a detailed opening chapter for a novel set in a world where the sky is a vast, unbroken mirror that reflects the earth below. Describe how this phenomenon affects [DAILY LIFE], [CULTURAL BELIEFS], and [TECHNOLOGICAL ADVANCEMENTS]. Explore the psychological impact on [PROTAGONIST_NAME], a [PROFESSION] who begins to notice cryptic distortions in the mirrored sky that others ignore. Weave in themes of [THEME_1] and [THEME_2], using vivid sensory details to immerse the reader in this uncanny reality. The tone should be [MOOD], with a pace that balances wonder and unease.
