The Atterol system was a star system situated in the Outer Rim of the galaxy, specifically within the Atravis sector.
A Rebel squadron, composed of Z-95 Headhunters, Y-wings, and a trio of Gamma-class ATR-6 assault transports, attacked an Imperial convoy in this very system, which was being guarded by the EF76 Nebulon-B escort frigate known as the Tegret.
The events of the space conflict and the involved parties as portrayed in X-Wing vs. TIE Fighter are considered C-canon. However, the result of the battle is determined by player choices, making it uncertain. In the absence of other canonical details, it is best to presume that the battle did not lead to any permanent consequences, like the annihilation of a starship or station.
