The Vulcans possess a sophisticated, ancient culture with customs dictated by their devotion to logic. Prior to the teachings of Surak, Vulcans lived in a culture of violence and war. Surak taught the Vulcans how to bury their emotions and live by logic. Vulcans live by logic in all walks of their life. They see violence as wasteful, but are logical enough to know that sometimes, force must be met by force. When a Vulcan comes to this conclusion, they become a formidable foe as they are anywhere from three to five times as strong as Humans.

Every seven years beginning at age 14, Vulcans experience Pon farr, in which the mating urge emerges with irresistible force. A Vulcan who does not mate suffers a fatal neurochemical imbalance. He may also experience plak-tow, the “blood fever,” when he loses all control of his emotions and can fight and kill without hesitation.

Vulcans are able to perform a mind-meld, which links their mind together with another and allows them to share memories, coming from their intensive mental training.

Personality: Vulcans suppress their emotions in favor of a rigidly logical approach to life. They frown on displaying or relying on emotion. They often have difficulty relation to emotional species. But one important thing to remember about Vulcans is that they do have emotions, they just choose not to express them or allow them to cloud their logical judgments. Vulcans have a natural affinity to the sciences, which are generally logical. Vulcans often leave their homes in the pursuit of knowledge and science, rarely for power, glory, or wealth.

Physical Description: Vulcans have the same average height and weight as Humans. Their eyebrows possess a distinctive upward slant, and their ears have points. Their skin tones range from olive to dark brown, in part because of the green cast provided by their copper-based blood.
