Baba Yaga's Dancing Hut
The Queen of Witches, Baba Yaga, lives in a small hut that walks all over Faerun and tales say across the planes on huge chicken legs. The party encountered the Dancing Hut when tracking down Jarath and Elaith deep in the forests of Chondalwood. True to its name, the hut ran around dancing about kicking and thrashing and spouting flames from its chimney. It was quite a battle just to settle it down and get inside.
Once inside, the party found the hut was vastly larger than expected. It seems to hold a multi-dimensional collection of rooms connected by magical portals. There are powerful curses that can afflict trespassers.
