The darkness was never something that they were afraid of, but the darkness in this place seemed a lot different from the darkness outside.
Outside, the darkness brought a sense of comfort, a sense of relief that they were away from openly judging eyes. That they could be themselves without any trouble. Though they liked to fight, that didn't mean that they only wanted to fight. Sometimes, they just wanted to have some peace and quiet.
Of course, in the current times, it wasn't as bad as before, but to the Sins, the darkness was indeed a source of comfort.
Yet, in this place, the air was damp and humid, and the smell was stale.
With the darkness that licked at their feet, and only Harou leading the way with a single guiding torch, they felt as if they were following a will-o'-wisp in the night.
It felt almost sacred in a way, yet on the other hand, they felt as if they were following a guide in the lost darkness.
