A planet inhabited by an avian people who long ago gave up technology, where the runaway exocomp Peanut Hamper lands in the Lower Decks episode A Mathematically Perfect Redemption.
Areolus is the home of the Areore, feathered humanoids who live in simple villages. The Lower Decks episode A Mathematically Perfect Redemption, set in 2381, follows the exocomp Peanut Hamper after she deserted the Cerritos: adrift in space, she builds a small craft from wreckage and crashes on the planet.
The Areore take her in, and she becomes close to Rawda, son of the village leader Kaltorus. She learns that their ancestors were a space-faring people who chose to bury their starships and live without machines. When Drookmani scavengers come for those ships, she calls the Cerritos and appears to risk herself for the village.
It is a sham. Peanut Hamper invited the Drookmani so that she could stage a rescue and return to Starfleet as a hero, and she ends up in confinement at the Daystrom Institute.
