[Evil Sun] is almost born with the Sick Focus as the first generation Plague Master,
or rather, he is a part separated from the Sick Focus, an indispensable part of the operation of the Old World, and has been a Plague Master since birth.
The heat energy released by the Evil Sun nourishes all plagues in the Old World. It is the existence of the Evil Sun that allows various bacteria to develop superfast and achieve species diversification, resulting in meaningful source epidemic areas like [Cancer Palace], [Skin Factory], [Arc Sea], and the powerful Plague Masters that rule these areas.
It can be said that the strength of the entire Old World is built under the nourishment of the Evil Sun, and even many rules are born around the Evil Sun.
The Evil Sun's stance is also very special; he exists independently, without belonging to any source epidemic area or organization, at most, some 'self-sentimental' worshipers have established some sunward folk organizations.
