Plum Mordosié

Plum Mordosié (プラム＝モルドシエ) is a magician who was making use of a shared ceremonial ground hidden in a container yard in 's harbor district.

Appearance
At the time of her interrogation, Plum was wearing a bloody mourning dress and glared with a sticky look in her eyes.

Personality
Plum thinks highly of herself and her abilities, considering her murder plan brilliant and that no one could ever follow her logic. She also considered the target of her revenge a "holier-than-thou asshole". While keeping the target of her revenge secret, she let Agnese affect her attitude during the course of her interrogation, making it seem unlikely to Agnese that she had much of a plan and that her revenge would come to fruition.

Background
Living in Calais, Plum sought revenge against someone for revenge and plotted to kill them by extracting their body using the three alchemical principles in a summoning ceremony, disrupting their internal balance and causing them to be destroyed by the power they were attempting to wield.

Within the month before the Hood summoning incident, she made use of the shared ceremonial ground run by Jack Prometeria, unknowingly becoming part of the summoning ceremony which Jack intended to use to summon the ship.

Toaru Majutsu no Index SS: Agnese's Magic Side Work Experience
As the phantom was approaching Calais, she was abducted from her home by Anglican agents and brought to the container yard for interrogation by Agnese Sanctis, along with the other magicians who had used the shipping container in which the summoning ceremony was performed. Answering truthfully about what they were doing, none of them knew the required exorcism procedure as they were not aware of being part of the summoning ceremony to begin with.

Abilities
Plum's exact capabilities are not known, though they are probably not as brilliant as she believes they are. As part of her murder plot, she planned to use the three alchemical principles (salt (body or base matter), sulfur (soul) and mercury (mind)) in a summoning ceremony to extract her target's physical form. With the supporting pillar of the body removed, she believed her target's internal balance would be lost and they would destroy themselves with the power they were attempting to wield.
