A demonstration took place at the Circle Bay mayor's office which is located on the planet Nubia, all during the time of the Galactic Empire's reign. Wullf Yularen, a Colonel, together with Captain Thrawn, conducted an inquiry into the demonstration; they determined it to be quite unusual and suspected that Nightswan, their adversary, could be planning to attack Imperial government personnel on Coruscant through the utilization of dojos and groups outside the government, for example, the Higher Skies Advocacy Group.
