Interstellar Union

In an alternate timeline where Vulcans had remained a violent and emotional species, the Interstellar Union was the organization formed by the coming together of Andor, Earth, Tellar, and Coridan III.

By the late 23rd century the Union included other planets and species such as Yridia, Risa, the Nausicaans, Rigellians, Orions, Caitians, and the Trill. The Union had its start in the form of the Andorian Empire which had subdued other rivals such as the Tellarites and Xindi, and manipulated minor powers such as Earth and Nausicaa. Later it became an economic body intended to offset the growing strength of the Orion Free States, and eventually transformed into a political union. Unlike the primary universe in which Earth was the Federation political capital, in this timeline, Andor was the main political capital with the Andorian Interstellar Guard serving as the Union's main exploratory and defensive force. Andorii was the primary language of the Union, and the organization was governed by the Union Prefect.

By the late 23rd century, the Union's attention was focused on the Klingon Empire as intelligence reports stated that the Klingons had conquered Gamma Hydra and reached their maximum coreward expansion prior to the Typhon Expanse. Fears mounted that the Klingons would soon turn their attention to the Union and invade via Vulcan. As a result, the Interstellar Guard had constructed a surveillance outpost on the planet to observe the primitive Vulcans in hopes of using their telepathic abilities against the Klingons.
