Once the devils were down Aeriyon could pass on the information garnered from his visit behind those doors and would inform the Matron, Elvas and the Blackguard (and her dragon) just what was behind that door. One Brachina? with a strong suggestive aura that didnt' seem to be hostile outwardly but he believed it could just be a ruse and that she could be waiting for an opportunity to do try or do something.  But he'd do it in dark sign so that the "victims" on the otherside of teh door wouldn't hear him informing them. He couldn't open those doors if he tried, he simply didn't have the ability to do it. He glanced at Xhyri for a moment, figuring that a handmaiden of Lolth could easily bypass that door if she truly wished. As well as the charmed drow woman kneeling in sublication but hadnt' seemed hostile either but was obviously being affected by that devil probably through some magic.
