"The medium through which that woman spread this cursed plague might have been intimate contact, or perhaps a kiss. Completely contaminating a corpse through such a symbolic act was very simple for a Mermaid's follower. What we need to focus on now is whether only those who died after having their Spiritual Power drained became contagious, or whether anyone whose Spiritual Power she drained would inevitably develop problems."
"Fortunately, this supernatural plague does not affect Ring Arcanists. Even so, I can hardly imagine a scene with hundreds or thousands of Infinite Snakes appearing on this island."
Although Fatumonst Island was a small place, the City of Time Wheels was still a city-level settlement. There were still quite a few people when outsiders and locals were counted together.
Although the island's total population could not compare to densely populated and prosperous areas like Tobesk or Moon Bay, it certainly could not have fewer people than the City of Thousand Trees—Vesta City.
After sharing the intelligence, Mr. Mortis hurried away. The Clown Troupe had already mobilized in full to track down that woman, and they suspected that Desire was working with Mr. Snake.
However, Shade also told Mr. Mortis that he would need a Ring of Fate compatible with himself if he wanted to participate in the final act of the battle for the Fate Chosen One.
Not long afterward, the Ring Arcanists sent by The Church to explain the situation to the town brought back similar news. Their intelligence was even more extensive than the Clown Troupe's—
"Earlier this afternoon, Lomari City also discovered cases of Snake Human Disease. Although the infected person had only left Fatumonst Island shortly before this blizzard, it is currently unclear whether he was infected before or after leaving the island."
