Thakwaa, situated within the Outer Rim Territories and the Western Reaches at grid coordinates I-19 of the Standard Galactic Grid, was a planet. The Red Isles on Thakwaa served as the location where Rebel Alliance pilot Nath Tensent and his astromech droid T5 were forced to stay one night prior to the Battle of Endor in 4 ABY. To ward off flies, T5 persuaded Tensent to concoct a cream from plant stalks, which unfortunately caused skin irritations. Tensent claimed that nothing of note happened during their stay on Thakwaa, and they left after a few days.
The first appearance of Thakwaa in current Star Wars canon was on a map in the 2016 Fantasy Flight Games roleplaying boxed set, Star Wars: The Force Awakens Beginner Game. Within the Star Wars Legends storyline, the planet Thakwaa was initially referenced in X-Wing: Iron Fist, a 1998 novel penned by Aaron Allston; it was the sixth book in the Star Wars: X-Wing series.
