The group was hired by The Church of Ecstasy to capture the demon called The Radiance so that the church can use that to transcend their humanity.
The group was sent over to Whitecrown with Malista in order to use her new shape to lasso it and then transport it back to the Church.
Malista managed to successfully capture the Radience and store it inside of her power core, but it did cause her to glow like the Radience.
The Long bridge to Whitecrown has a lower walkway that the servant class uses to get back and forth across the bridge without being seen by the upper class.
