Roman Dayan: Part of why I was dispatched here is because I Roman Dayan: have a strong immune system. Have you Roman Dayan: experienced any headaches or bouts of coughing Roman Dayan: since you came here? NakanoAzusa: No, I haven't. Roman Dayan: Oh... you must have a strong resistance too. The Roman Dayan: Dark Legion was successful in contaminating the Roman Dayan: area but once Aitan came it got harder for them. Roman Dayan: So they began spreading this epidemic. NakanoAzusa: Our presence is the reason behind it? Roman Dayan: Yes. As it progresses, blisters will appear and Roman Dayan: eventually the victim will die. However, a few Roman Dayan: Aitan are immune. A vaccine is being made Roman Dayan: at the Basilica Giovannis from their blood. NakanoAzusa: That's good, but it takes time to produce vaccine. Roman Dayan: True. That's why I think we need to reduce the Roman Dayan: amount of medium that's spreading the disease. NakanoAzusa: What is the medium? Roman Dayan: Contaminated Caelium near the Yard of the Prophet Roman Dayan: produces a yellow flam when you shock it. Roman Dayan: These Plague Flam are the cause of the epidemic. NakanoAzusa: Caelium... contaminated? HiiragiKagami: Hoowhoa! I'm starting to get dizzy. May be... Roman Dayan: Haha! Don't worry, Pran are immune to it. HiiragiKagami: Oh... really? Roman Dayan: Please help us stifle the spread of this disease.
