Your instincts were correct. This is the swamp from the final panel of Bard Quest. It appears you all must gather here and wait, as usual, for Bard Quest to resume before anything else happens.
There is nothing more to do in Jester Quest. Nothing left to prove. No lessons to learn. No character arcs to complete. All that there is left is what has been here all along. A beloved but unfinished tale named Bard Quest, which you must patiently wait to unpause.
And wait you will.
THE END.
