Armus IX was an inhabited planet. It was the ninth planet of the Armus planetary system.
Prior to stardate 41636, William Riker had to wear a costume decorated with feathers during a diplomatic conference.
In 2364, Riker referenced this event in a conversation with Natasha Yar and Deanna Troi in his preparations for his meeting with Beata, the Elected One of Angel I, on the lengths to which he would go to meet local customs. (TNG: "Angel One")
Presumably, Armus IX was located in the Alpha Quadrant.
The planet might have been named after TNG writer Burton Armus.
