Though she was corrupted by lust, Gabriella remains a powerful threat. Her powers and their containment procedures go as follows:
Immortality - As Gabriella cannot starve, feeding her is unnecessary, and so is removing her gag.
Divine Freedom - Gabriella can escape any restraint at will, save only for those applied by her owner. Miss Vi's strict bindings are the only way to secure her.
Telepathy - Gabriella can communicate with nearby minds telepathically. To prevent her from calling out for help, she must be kept in the isolation cells at all times.
Magical Surge - Given enough time to concentrate, Gabriella can unleash a surge of magical energy, potentially knocking out all guards and prisoners alike. Regular teasing, orgasms, or denials will break her concentration.
