Elaan, an Elasian female
Kryton, an Elasian male
Elasians are a humanoid species, native to the planet Elas of the Tellun system.
Federation scientists described Elasian males as "vicious and arrogant" in early reports. Females had the ability to produce Elasian tears, a biochemical compound transmittable to males (including Human men) upon contact. The affected man became romantically infatuated and somewhat enthralled to the woman who infected them. Over centuries, men of Elas tried to overcome the tear's power, without success.
In the 23rd century, Elasian government included a Council of Nobles, and great homage and deference was paid to their royal Dohlman. Their technological level was pre-warp; with nuclear powered weapons and vessels. Some Elasians wore a light and translucent body armor.
Elasians considered themselves a warrior people, and held little regard for the relatively gentle culture of their neighbors, the Troyians of Troyius. By 2268, after a long period of war with the Troyians, the two civilizations recognized the possibility of their mutual destruction. Some hope for peaceful coexistence began when elements of both governments supported an arranged marriage between Elaan, the Dohlman of Elas, and the ruler of Troyius. (TOS: "Elaan of Troyius")

Background
In 2268, the Prime Directive did not seem to be an issue for the Federation in the Tellun system. Pre-warp Elasians did not appear to be surprised or impressed by beaming aboard a starship. Some level of contact between Elasians and Klingons had already been established: Kryton's cooperation in sabotage of the Enterprise, and the Empire's existing awareness of Elasian dilithium deposits.
