From what I can tell (I'm not sure because I didn't write the first part of the story, so I'm kind of talking out of my ass here) Grodus got into contact with Atsaan... For some reason... And Atsaan basically promised him infinite power or something in exchange for freeing him with the relics, and then pointed him in the direction of where the map was being held.

Erm, I faintly remember it being mentioned in Trix 2 that the Ao Oni was originally not bad, but after he and Rebecca explored the mansion, which was haunted by ghosts, Ao Oni got possessed and became the demon he is now. At least I think so.

Zalgo's a tricky thing to defeat, yo.

Unfortunately, probably so. I had an idea involving Shattered Families and the curse having to do with that, namely the witches getting killed in the area, and them cursing the region al la salting the earth, and that's part of the cause of the crazy shit that goes down in that area, but I don't know how well that could work out, especially given I'm most likely not going to finish that story.
