I finished the unbound-controlling task for the Drakon Warmaster of Northforge. I also checked on the Shapers hiding nearby as per the drakon's request, and I agreed to help Melinda and Alwan in their attack. But, I have no intention of actually helping the Shapers at all. I'd like to report the Shapers to the Warmaster, but apparently he's already in the Inner Shaping chamber, which I don't have access to. I've talked to Jared and a few other semi-important npc's, but they've just told me to enter the Inner Shaping Hall. How can I get into the shaping halls at this point without aiding Alwan?
