Lately, I've been feeling unsettled. It's hard to explain, but I felt a weird shift in the flow of mana. The mana hasn't increased or decreased significantly, but it feels off. I talked to Raine and Sheena about it, and Sheena mentioned that Presea told her she felt sick recently, almost like she did when we were collecting the Devil's Arms years ago. We defeated Abyssion, and I burned the Necronomicon myself, but we never actually destroyed the Devil's Arms.
I don't see how Abyssian could have returned, but we're all going to the Temple of Darkness with the Devil's Arms soon just to be safe. It may be best to destroy them after all.
I heard once that the Necronomicon was originally written on scrolls and then later copied into a book. The scrolls have never been found though, so that story remained a myth. I'm probably overthinking this, but if someone got their hands on those scrolls, we could be in trouble...
