An ancient mountain-top observatory carved into living stone, where the amber windows thickened with age now crystallize the starlight into readable tide-patterns.

The Spire predates the empire, built by forgotten hands who first understood the Sunken Star's code. Its great telescopes are lined with lenses of naturally grown amber, and its library floors are paved with preserved tiles that crack like glass underfoot. The Starseekers here maintain the Tide Almanac — the single most valuable text in the empire, for it tells lords when to flee and merchants when to harvest.
