After about the time it took to drink two cups of coffee, Dora had explained the situation under Mo's guidance, which wasn't complicated. Aside from quickly glossing over the part about 'just how powerful the Black Fan Commander was'—a detail neither probed further—the whole process was actually not hard to explain.
Simply put, Dora was taken by the High Priest to a chapel's underground prayer room where she met a group led by a certain clergyman. She was then questioned about the command details of the battle in Misha County, strongly criticized the commander from the Dawn Religion, and was taken by the High Priest she first saw to the sewer. There she received what seemed to be a powerful item and was sent away, only to be knocked unconscious when she had just returned to the surface; she woke up here.
Despite this being her first meeting with Mo, and the place being the somewhat awkward small court, Dora didn't hold back, not even she knew why.
