The Three Plaguemaidens
Written in the lore books held by the holy paladins of Lorenia, the entire goal of their holy order was to stop the evil within the lands of Azanoran. The last adversary written in the lore books were the Plaguemaidens.
Originally, two beautiful hags traveled across Azanoran, spreading disease and pestilence as they went, causing the deaths of thousands. Throughout this time, they had bedded with many men, having many children that they left behind, these children were the first of the Garkains. These plagued creatures spread plague and pestilence, infecting others, and ultimately turning them into Garkains as well.
There was one point where they kept a child. No writing can verify whether it was theirs, or just a kidnapped child, but regardless of either fact, they raised this child, and they became the third Plaguemaiden.
