According to the information they had received, there were only two other superior Demons on Azura besides the Supreme Commander... Well, three now, if you count the one who had taken on the appearance of Kilian and who could not be detected earlier because the Mages and Papermakers of Azura did not have the knowledge to use the Rune of Revelation.
And when Dylan and the Warrior of the Universal Organization had made contact with the rebels, they had been unable to get into that building undetected because it was so well guarded, so they had not been able to unmask this superior Demon.
All they could do was confirm the information the rebels had given them and verify that the capital of Azura, where this building was located, was not overrun by Demons.
