The Angel I natives were a humanoid species from planet Angel I. In appearance, they resembled Humans. The name of the species was never revealed, females tended to be taller than the males. Their society was highly matriarchal and their government, the Parliament of Angel I, consisted of six elected Mistresses and a female Elected One. Men were considered second-class citizens.
Their civilization had reached the technological equivalent of Earth's mid-20th century by 2364. First Contact with the Federation occurred in 2302 when a Federation vessel visited Angel I. The freighter Odin collided with an asteroid in 2357 and escape pods landed on Angel I. The next contact with the Federation occurred in 2364, when the USS Enterprise-D visited the planet.
