History:

 With the devastation of their war, the remaining Talosians retreated underground below their planet's surface.  They found this life highly restrictive, and so devoted themselves to developing a tremendous level of telepathic ability. This ability proved to be the downfall of their race. The Talosians enjoyed sharing the experiences of those aliens they had collected prior to the war, becoming almost like a narcotic for them. They came to rely on their fantasy life more and more, eventually losing almost all touch with reality. As a result, their technology crumbled and decayed around them to leave them all but helpless
  The Talosian response was to bring aliens to their world, hoping to select appropriate specimens and use them to breed an entire race of slaves to maintain their society while they continued to enjoy their telepathic fantasy lives. The first encounter between Talosians and Humanity came when the SS Columbia crashed on Talos IV. One woman named Vina was the sole survivor of the crash though badly injured.  The Talosians repaired her injuries, but although they found Humans to be an ideal physical choice for their slaves they were not able to proceed with their plans for a further 18 years due to the lack of any male candidate
  18 years later, the USS Enterprise, under the command of Captain Pike, encountered a distress call sent by the Columbia and proceeded to Talos. The Talosians kidnapped several crewmembers, including the Captain, in order to start their slave race. Pike made every effort to escape, but the Talosians mental abilities made it all but impossible - so complete were their abilities that they could easily destroy the starship just by tricking the crew into pressing the wrong buttons.
  Pikes first officer threatened to kill all of the captives rather than submit to slavery. Realizing that the Humans would never accept captivity, the Talosians allowed them to leave
  The Federation quarantined the planet, forbidding any Starfleet ship to approach.
  Years later, the USS Enterprise was hijacked by its first officer Spock, and taken to Talos. Captain Pike had recently suffered devastating injuries from exposure to delta rays crippling him as a result.  Convinced that Pike could live out the rest of his days more comfortably on Talos, where his mind could be convinced that his body was once again healthy Spock hijacked the Enterprise.
