Pandora/Relationships

Emilia
She seeks her for some unknown purpose, that involves a giant black door deep in Elior Forest.

Regulus Corneas
Pandora persuaded Regulus to accompany her to attack Elior Forest. Also, Regulus refers to her with an uncharacteristic amount of respect, likely due to her being a higher-ranked member of the Witch Cult.

Echidna
Unlike the rest of world, Echidna seems to at least be acquainted with Pandora, describing her to be the Witch of Vainglory to Emilia during her trial. However, she is dismissive of Pandora's power, claiming that it made her an expert at saving her own skin.
