A flickering ancient light deep in the heavens that governs the amber tide's rhythm — when it pulses bright, the petrification accelerates; when it dims, the waters recede.

The Sunken Star is not a true celestial body but something older — perhaps the fossilized heart of a fallen titan, preserved in the void and burning with trapped amber-fire. Astronomers at the Spire watch its flickering patterns like reading a language, for the Star's pulse predicts the tide's advance. Cultists whisper that it dreams beneath the crust, and that the amber rising is its breath, not its wrath.
