When the demon's scarlet eyes looked at Charlie, Lucien noticed that Charlie's face froze immediately, and the symbols on the magic shield started to swell and break into pieces. Then, the whole shield was destroyed. As soon as the shield was gone, Charlie was enveloped by a heavy black fog.

After a second, the black fog disappeared all of a sudden. A small black pig showed up at the spot where Charlie was, and it looked beyond lost. Turning around in circles, its thin tail kept wagging.
"Baleful Polymorph!" Sandra's voice came to Lucien's mind through their telepathic bond, "We need to kill it before it gets out of the brazier!"
At the same time, dark clouds gathered under the celling. Among those clouds, streak lightnings were flashing, turning the whole place into a lightning forest.
