Willight Riziem Ernst is the attendant of Juclecia.
The "real" Juclecia died many years ago. The Juclecia that returns to Shudelmir to exact revenge on the royals is a fake created by Willight using the Emblem. The Emblem imbued an outer appearance and memories of Juclecia into Adora.
Because Adora was impersonating Juclecia, albeit forcibly, she was sentenced to death by the Shuldermir nobles.
He is a non-playable and non-fighting character.
