Apate

Apate is the daughter of Erebus and Nyx, a member of The House of Erebus, Goddess of Deception, later Goddess of Truth.
Mother of Ford Corvin, The Warchild.
Beloved of Fionn Corvin.
She first appeared in Season 2.
In her first appearance she tricked Fionn into rescuing her from Clearwater Asylum, masquerading as 'The Real Simon Prince', a kinder and gentler version of Prince.
She revealed herself to be Apate after escaping.
She was sent to Fionn's Halloween party to seduce him, taking the form of Jenny Swanson but he recognized her through the soulgaze, warning her not to take the form of a loved one again.
Later that night they met in the gazebo and spent a while talking, this was the beginning of the bond between them because Fionn felt some sympathy for how she was forced to serve her Aspect rather than vice versa.
She joined The Squad and fought in the The Tartarus War.
She mastered her own aspect and joined House Corvin as Goddess of Truth.
She and Fionn had a child, Ford Corvin.
