The Taa Complex, a subterranean greenhouse featuring gardens on its roof, existed within the Raddakkia Plaza on the world of Troithe and utilized a climate control system. Circa 5 ABY, during the conflict that occurred on Troithe pitting the New Republic against the ruling Galactic Empire, Acting Governor Fara Yadeez along with Colonel Soran Keize of the Imperial 204th Imperial Fighter Wing frequently strolled through the plaza and on top of the Taa Complex. Subsequently, a memorial service was conducted inside the complex for Garmen Naadra, an aviator from the 204th, and Keize shared anecdotes about the airman with her unit by a bonfire constructed from limbs gathered from the Taa Complex's gardens.
The Taa Complex was featured in the 2020 novel titled Shadow Fall, authored by Alexander Freed.
