Bridge of Dusk

The Bridge of Dusk is considered by most to be the greatest architectural achievement in the known world. It connected the two continents, Thyra and Thassos, spanning 70 miles over the ocean. It was built by the mages of the Opal Spires and the Artificers of the Cities of Steel, who were also responsible for its upkeep.

The Thyran Empire occupied the bridge and used it to secure their trade routes tariff-free, claiming that since it outlet at the Thyran city Ryu, the bridge was rightfully theirs. When the cities of Chenal and Tarbad retaliated, the Opal War begun. The bridge was eventually cast into an ethereal state by the head of the Opal Spires, Ryudun, with the help of bound outsiders, killing ten full units of the Thyran Host and rendering the bridge unusable.
