After completion (spoilers)
"We will resist until the very end." You transformed into a Kobold with Cecilia's illusion magic. After having its effectiveness confirmed, you slipped into the fortress ruins, where it quickly became apparent that Krall attention was focused on the command post. After cutting through the Krall and reaching the command post, you learned that Reda had made her last stand in the Illusion Oratory. Entering the Illusion Oratory required Kaisinel's Seal, and Phernos suspected that the seal would be found in the Illusion Sanctum, where the cavaliers had made their own last stand.
