With everyone's explanations and additions, Angel gradually understood the general situation of this matter.
For some unknown reason, a disease that turns people into madmen is spreading heavily in Windmill Town. This disease also has a very strong contagion; anyone who has been in contact with a patient has a high probability of being infected with the madness.
Moreover, even after the wizards of Barbarian Cave were alerted, there was still no effective treatment. The wizard's final solution was just to restrict the patients in a special asylum, preventing them from having the chance to infect others.
Greya: "So, you're saying that the Yva you mentioned has been confined in the asylum?"
Everyone nodded: "Yes, Yva was clearly put in the asylum, but somehow appeared in the cave."
