Selar (mirror)

In the mirror universe Selar was a slave on the ISS Enterprise-D in the Terran Empire's final days of its war with the Klingon-Cardassian Alliance. She was reluctantly appointed the Enterprise's Chief Medical Officer as she was the only one on board who was still alive and had the medical knowledge necessary, Beverly Crusher having been disposed of by Captain Picard and Deanna Troi. While most humans blamed Vulcans for their Empire's misfortunes, one human, Wesley Crusher befriended her because he realized what Spock and others had tried to offer. They later fought together in the Terran Rebellion.

Selar tought Vulcan mind techniques to Wesley, whose understanding of the relation between space, energy, and thought enabled him to overcome his human limitations, enabling him to perform mind-melds with both humans and Vulcans.
