In Attack of the Clones, a hive spire served as the command center for the Droid Army fighting in the Battle of Geonosis. A landing platform was located at the spire, from which both the Separatist Council and Count Dooku himself fled after being defeated by the Clone Army of the Republic. On the platform we saw personnel who were not Geonosians (no wings, but funny hats).
Who were they?
