The set is base on Count Dooku’s secret hanger on Geonosis. The set comes with 4 new minifigures and 3 exclusive Minifigures (FA-4 will also be released in 75023 Star Wars Advent Calendar). The set features several arches that represent the curved Geonosian architecture seen within Dooku’s hanger. Connected to the arches is a large archway with a landing pad for Count Dooku’s speeder.
Attached to the top of the archway is a light fitting. Next to the entrance is a hidden storage compartment for
Dooku’s Force Lightning.
One of the play features is a column which has a lever that can cause it to topple over. This is reference to a scene in the movie where Count Dooku causes a column to fall over with the force.
Attached to Yoda’s back is a bracket that is attached to a pole so that he can be moved about to re-enact the flips he does in the movie. In Poggle the Lesser’s hand is a LEGO brick that represents the Death Star plans he later gives to Count Dooku. FA-4 acts as the pilot of Count Dooku's Solar Sailer despite it not being in the set.
