Cygnian

Cygnians are a humanoid species native to the Omega Cygni system in the Alpha or Beta Quadrant. They are characterized by their cat-like eyes, and by their sympathetic psionic abilities which allow them to perceive the actions of others within a certain range.

Sometime prior to the mid 23rd century, a Cygnian named Magen became stranded in Elysia, and eventually became a key member of the Elysian Council. 

Cygnian respiratory diseases were a topic of interest to Federation medicine in the 23rd and 24th centuries.
