7 Wonders

A sai scholar named Dool D'Shoog in Dullhost compiled a list of the greatest items of the seven races

Reachmen - The Escapement
Underneath the Clocktower in Telos.

Sai - Heartforge
Super awesome forge in Vega.

Kin - Tree of Life
Unknown location, perhaps hidden in Menkara or high in the Sakir Tep

Dos - The Voggan Schematics
The original plans for airship technology are lost and it is currently unknown how to build new airships, though the ones that are operational now can be maintained and repaired as needed. Perhaps one day the original blueprints will be found, or the secret re-discovered.

Sior Voggan is the Dos folk hero to whom the first airship construction is ascribed. Whether he engineered the device from scratch or simply uncovered and popularised the design is a matter of debate. There is some evidence that the popular figure may be a composite of several historical entities.
