I say provide some information in the authors notes with a spoiler warning before it. As for the way the worlds acting any one thats played Silent Hill or read a Warhammer novel could tell you space is being distorted baring any dream nonsense, rooms,doors and places are being rearranged like a child building blocks linking one to the other for a limited time only for them to be torn asunder again.The big questions are is time being distorted as well? Is this all of this being controlled by some fel intelligence? Do the changes fallow some sort of law or pattern? Also if your having trouble rapping your head around that watch a movie called Cube 2: Hypercube about average as movies go but i think it got the ideas explained right maybe... haven't watched it in a while truth be told

This story is entrancing, and at the same time very disturbing. I'll go ahead and follow this.

Ah, I don't know if I missed it in Coco's chapter or if they just didn't notice, but both the desaturation and the aging effects were preceded by a few moments of silence, but it seems the appearance of the monsters wasn't.

Babs seems like the sort of filly to keep trucking on, even under the horror she's all seen. As you mention in your author notes, however, she's definitely out of her element since this is several magnitudes of disasters more cruel than she would have witnessed before, something even her nightmares couldn't begin to approach. For Babs, though, it's possible the only thing keeping her from breaking down is that she's been forced to keep moving. Once the creatures stop coming around, she'll have a break, only to realise that both her sister and her cousin are likely dead.

It seems that this had all started when Discord opened the box. Which means that the box might be home to demons that take form of the hunted's dark thoughts and memories, much like Silent Hill, the game this story is based upon. So this means once the box is opened, the demons then take form and torment the poor souls it has claimed to be it's next victims.
