Alumia

Alumia was a Lord of the Rings Mary Sue slain by Agents Dafydd and Selene. She was a woodsprite from somewhere around Angmar, and had the power to merge with things.

Character History
She was a Tenth Walker, created a legion of mini-Balrogs, and fell in love with Legolas. In fact, she was just about to bed him when Dafydd and Selene intervened. She promptly merged with Arda. That's right, the whole planet.

Character Demise
PPC HQ was placed on alert, and Agents from every department and fandom portalled to Arda to exorcise the world. Alumia was exorcised, Dr. Niamh of the Department of Mary-Sue Research and Experimentation removed a finger for study, and Dafydd unleashed the minis she'd created. Presumably, they devoured her.
