So, the guys who made that "Prey" video apparently had a brief stint in publishing d20 books.
The Redhurst Academy of Magic!Sounds really neat setting-wise, but how suitable is it for a d20 game? A game where the PCs are students seems geared towards a low-powered, all-spellcaster kind of group and doesn't fit with the standard "dungeon-delving formula" of many D&D campaigns. Regardless, the adventure ideas alone for it are brimming with potential!
