Etrusca (Official name: Republica Etrusca) was a core world of the Compact. It was noted for the language Neo-Latin. The planet’s star system contained one terminus of the Yaphit Pass, the only known passage to Thule, which sat above the galactic plane and was thus unreachable by projection drive.
Calpurnia Barratus served as senior delegate to the Compact Assembly in 430 IE. On behalf of the planet’s government, she put forth a successful measure to transfer authority over the fallen colonies of Farigha and Amargosa from Mars to Metis. However, while successful, the measure did not satisfy Metis’s demands to allow the former colony of Gilead to become the independent world of Hanar.
