As she battled her drowsiness, Arachne recalled her life so far, as she heard what Maria had to say. The sole concept of not being tied by the sin of Sloth anymore was something she had dreamed about so many times already, but that she never truly considered something real.
Why? It wasn't because she was just a child that had no idea about anything, but it was because of her very existence. Her birth, her very being, her everything…
Although some Calamities are chosen after growing up by the Calamity Seed, or have it transferred from another, deceased Calamity, there are also Calamities that are born to be them.
Arachne was one of them, the Sin of Sloth shaped her to become her vessel the moment she was born. She never knew something else, nor she knew any better.
Since she was nothing but a little spider inside an egg, that the Sin of Sloth made her its vessel, transforming her, and giving her the appearance she had.
