Aytar Gwyn was a female serving in Starfleet in the late-24th century. Gwyn was half Kriosian and, as such, had some emphatic ability. She had deep-blue hair and light brown geometric shapes running along her hairline.
Although a very competent pilot and a confident individual, Gwyn had, on occasion, been noted for poor judgement - including being late for duty following a sexual encounter with Ensign Mirren, the deltan conn officer of the USS Achilles. (VOY novel: Unworthy)
