In the dark mirror universe, the Terran Empire Alliance (TEA) is a strong and powerful military coalition created between the Terran Empire, the Centauran Empire, the Vulcan Empire, the Andorian Empire, and the Tellarite Empire in the mid-22nd century.
This Alliance was proposed by Charles Tucker III, the Emperor of the Terran Empire, and Empress T'Pol in late 2160, in an effort to build upon the work of the ISS Imperial One and organizing a joint military operation after the war with the Romulan Star Empire that same year.
Both the Denobulan Empire, and the Orion Empire later joined the Alliance, in hope of finding both alien and Terran rebels, and one day the Alliance would defeat the Klingon Empire sometime in the 23rd century.
