A bright and very technologically savvy thirteen year old, Jenny is the daughter of Violetta and Lumia McClutskey. Jenny had hacked Vik's computer while he was doing research into the family, then using her magical roots to scry on him and brand him with a necrotic mark as her way of sending a distress signal. Jenny had been worried about Lumia who had been deathly ill. When the party came to investigate on Eleanor's birthday, they walked into a warzone. During the assault on the McClutskey family house, Jenny managed to escape through the window and hide from the eldritch abominations that were threatening her.
Later on, the McClutskey family would fully be driven out of their home by the Eternal Beast. Jenny now resides with Eleanor, and while there hacked into the MBI's database. Uncovering secrets of Technomancy, Jenny confided this information in Bianca, Vik, Eleanor, and Deltane.
