The Slaadi have sent a raiding party. They’re able to somehow bypass the Wall of M’Drone and sneak in a half dozen or soo raiders into the realm of six circles. The Slaadi are ferocious and never let themselves be taken alive by the monks.. But the PC’s will not be recognized as anything more than a random threat. The slaadi may think they are a random encounter and there may be an opportunity to take a captive there. Use the chamber of circles to transport yourself and find them.
