Kieran was showing an expression of disbelief.
The Church of Shadows, although it was rarely mentioned by Sister Moni, it didn't mean Kieran didn't know of their existence or the influence they had in the current dungeon world.
Back when the churches ruled, the reason why the Church of Light couldn't reign over all was because of the existence of the Church of Shadows.
Both sides were arch enemies because of certain creeds they upheld, plus both Light and Shadows had no lack of frantic believers, the open and secretive battles were endless.
But the fact that the Church of Shadows separated from the Church of Dawn still made Kieran feel it unbelievable.
"This is really shocking!" Kieran was stunned for 2 seconds before giving such a comment.
