Wonders of Glass
Glass is peppered with a handful of strategically significant wonders.
The Lighthouse
Nearly omniscient vision over the entirety of the underground on this half of Aia. Was formerly used to suppress Impish invasions, then was later destroyed & abandoned during the Abdication War. Functionally allowed the discovery of most tunnel & mine networks across the underworld & allowed the mapping of the local Undergarden.
The Panopticon
Instantaneous undetectable real-time top-down vision of every location on Glass & on most of the surrounding islands & ocean in a spherical radius around the tower with fidelity sufficient enough to make out individual people by their dress, limited only by the focus & intent of the operator. Currently held by Lord Arcades; the Tower itself is built on one of the largest coastal sea-pillars in the Rim Arcades.
The Curtain
The City of Leaves, the historical capital of Glass, is built inside two massive concentric granite walls of nearly impervious engineering. The outer wall once held a substantial amount of farmland, but urban sprawl over time has resulted in its internal production being too low to support the population indefinitely. The Curtain is the only thing keeping the Regency in power.
The Theomni Templevault
A gigantic fortified temple-palace of ancient design built underneath the city of Theomni, one of dozens known to exist across Aia.
