Oberon

''Dean: "Why are the fairires abducting people?" ''

Marion: "Hmm. There is much theory and little fact. We know they only take first-born sons..just like Rumpelstiltskin did. Personally I think they're taken to Avalon to service Oberon, King of the Faerie."

Oberon, is the King of the Fairies, a race of magical beings from the realm of Avalon, a dimension seperate from earth. In Avalon according to Gilda, a good fairy, there also exists a fairy Tribunal, which her former master, a LARPer who had bound her to his will, would be brought before. It is not known if Oberon leads this tribunal, and his actual power, abilities, origin and appearence have not been revealed.
