Return of Tambelon (3)

With Megan captured, Danny takes the lead and suggests they find a way to destroy Grogar's magic.  Forget-Me-Not remembers that the bell he wears around his neck glowed when he used his magic in Tambelon.  Everyone decides that the bell is his power source and they can take it from him if they can make him leave the city.  They manage to do this with the help of Danny's tape recorder and one of Masquerade's disguises, but Grogar is too strong for them and madanges to capture a few more ponies while the others run away.
Megan and the prisoners try to find another way out, but there are no hidden passages in their new cell that lead to the city streets.  They mention the bell again, which Paradise thinks could have been an important part of the legend of Tambelon but isn't quite sure of.  Elsewhere, Danny and the others capture a Troggle who was deserting and wants to lead them to their friends before Grogar banishes them to the Realm of Mists that night.  They decide to trust him and let him lead them into the city, but they are all ambushed by Grogar and Bray and sent to prison with the others.
