An Imperial squadron of eight TIE/ln space superiority starfighters tracked members of the Rebel Alliance to a mansion owned by a friend of Captain Amilyn Holdo on the planet Spira after they stole a Nihil Path engine from a strikeship that had been won by the curator of the Imperial Museum on Coruscant during an auction on Spira. The squadron destroyed the mansion, but were unable to prevent the rebels from escaping.
