I'm definitely getting into the mapping zone. This is the third of the elemental halls connected to last week's entries. This one is a central cave that leads upward into an opening into the elemental plane of air... the evil magic user and his bugbear minions have been using giant bats to raid the cloud tower of a cloud giant far above, stealing roc eggs and raising them here in the cages (subjecting them to all sorts of mutations).
We'll be playing this Saturday night... I'll let you know how it goes!
