Ferretina

Title baddie ("badette"?) in the Revenge of the Weasel Queen radio play. She first appears here in a non-action stringer, and makes her first actual story-line appearance shortly thereafter, marveling that Agatha, Zeetha,  Krosp, and last but not least (except maybe in terms of competence) Othar Tryggvassen, Gentleman Adventurer, have managed to dispatch a pack of lapinemoths. (Little does she know.) She skillfully plays on Othar's basic cluelessness, spinning the tale of how the Weasel Queen has taken control of the town of Zoggletonk, without however revealing that she is the Weasel Queen. (Well, anyone with the brains of a cabbage should be able to figure it out, but that basically excludes Othar.) Like the Gentleman Adventurer he is, he gallantly offers to walk her home, and only after they stroll off does the unconscious Jorf Oxclonker, a villager who'd been menaced by the lapinemoths, inform Agatha, Zeetha and Krosp just whom they were dealing with. Part 1 of the radio play ends at this predictably cliff-hangerish point.

Ferretina shows up again as Revenge of the Weasel Queen, Part 2 opens. She conducts Othar to her hidden subterranean lair while the rest of the party decides whether to rescue him, and eventually, how to do it. Here she reveals her true colors (literally) and begins to plot his ruin, with a whole passel of additional lapinemoths (which she has created -- this a Sparky evil weasel queen...) getting involved. Even a dim bulb like Othar can figure things out at this point, and so Part 2 ends in another cliffhanger, leading to the near certainty that we'll be seeing Ferretina again. (Seeing lots of Ferretina again; her wardrobe isn't chosen for modesty.)

We don't really know whether Ferretina qualifies as a Spark, her lapinemoth-creation skillz notwithstanding (maybe it's a monsterish capability rather than a Sparky one), nor do we know whether this radio play is somehow going to connect to the main story. There will presumably be a Part 3 to this story, however, so stay tuned.
