I thought Gosh, that almost sounds like adventures in effulgence, but then the Chincher:"A potion of effulgence, to quench the purple fire," Professor Quirrell said. "It is made by adding the same ingredients, over and over again, in slightly different ways.

This room is the handiwork of the Potions Master indeed."

13 Adarins as far as I know... No! there's also the Witch adarin which summons Cam, so: 14 Adarins!
