Based on some permitting documentation in
@Alicia's latest podcast/video, it would appear that the town in the Monsters land has, indeed, been named Darkmoor.
I really wish they were going with something that appeared in the actual movies. Is it a huge deal? No. But it does support the idea that the land is going to be "inspired by" the movies, rather than a direct recreation of the IPs. I just hope they don't go too far afield.
