Prompt: Creepy
Their new home was rather creepy, even by dark guild standards, with the cave complex descending a little deeper into the earth than they had initially scouted, and the echoing sounds of dripping water from within (plus the resident bats) could keep anyone up at night even if they didn't share Macbeth's nocturnal disposition.
But having the internal clock that he did, Macbeth was the least affected by the peculiarities of the caverns at night; he was long since familiar with the way shadows moved differently, and how disorienting darkness could be for those who weren't used to it.
Which is why it surprised him that sometimes Erza would keep him company through the deepest part of the night – after all, it wasn't as if he needed any reassurances.
But then again… maybe she did.
He was more than a little disturbed by how much he minded that she sought him of all people out.
