Fellnight Queen

"Realm of the Fellnight Queen" is a 7th level Pathfinder adventure that could be easily adapted for 4e.  A fey/shadow sorceress was imprisoned in a demiplane, which has now been breached.  The adventure starts with a disgruntled gnome bee keeper siccing his bees on a wedding, and the third encounter is called "Drunken Treant".  What isn't to love about this?
