Vulcan (planet) (AMU)

In the alternate mirror universe, the planet Vulcan was at first a world of status within the Terran Empire and the homeworld of the Vulcans. Spock warns Sulu that if anything were to happen to him that "my operatives would avenge my death, and some of them are Vulcans." 

History
The events surrounding how Vulcan officially became a part of the empire following first contact with Terrans in 2063 have been lost to time. Some say the Vulcans joined the empire believing they could manipulate Humans from behind the scenes, while still others suggested that the Vulcans joined feeling a sense of weakness and a need for self-preservation. Having fought a devastating war against the Romulan Star Empire between 1939 and 2041, it could be the latter case which prompted Vulcans to offer themselves as vassals of the empire, rather than full partners. Whatever the case, Vulcan and its people would play a key role in helping to expand the borders of the Terran Empire.

T'Pau, who had been a minor diplomatic official at the time of first contact, would eventually become Vulcan's head of state. It was through her actions and her ability to manipulate one Emperor after another that allowed Vulcan to be both a vassal world within the empire and yet maintain some of its autonomy. Initially T'Pau lured emperors into her bedchamber through her own charms, but then later used a cadre of seductresses in the Imperial Palace to sway and influence the empire's officials. Her agents were equally adept at wielding psionic powers and had access to a huge collection of ancient Vulcan poisons which alluded medical detection.

During the glory days of the Terran Empire, T'Pau, the reclusive mistress of Vulcan lived in a citadel on the Plain of Tai-La. Its roofs had gleaming liquid ludugial gold held into place by force fields. There were also musk-scented corridors, secret passageways, spy holes, a treasury and a torture chamber. Throughout the huge complex walked servants, many of whom had had their eyes or tongues cut out. Those who were blind moved about through clairvoyance.

Despite the conditions on the surface, the Vulcans never abandoned their homeworld. What's more, they continued to run most of criminal gangs who dominated the planet's population. Terran officials chose not to bother with any form of warden station and simply monitored the planet from orbit to ensure those sent to Vulcan never left.
