This adventure was entirely the Dungeon 211 adventure: Glitterdust

 

The heroes played as several level 1 pixies.  Instead of Acorn simply telling the heroes the story of where the found the Flame of the Frost Giant, the players acted out the story by playing Acorn, Pep’r Potz and several other pixies as they rescue Glitterdust from an evil bog hag.

 

The candle that Rotten Ethel uses to chase Glitterdust in her cage is actually the Flame of the Frost Giant.  Ethel doesn’t know how powerful of an artifact she has in her possession.

 

What happens to the candle and where it is now depends on what the heroes do in this adventure.
