This is a book written for the D20 system that goes above and beyond what most books written for D20. It is written as a text for a magical academy but it is written in character. I do not think they released another product in this line and it is a shame if they didn't or if they did I do not know about it. I think the resemblance to Willow (slight but there), or maybe a hot elf chick, has something to do with the initial appeal. Once you open the cover the book sells itself though.
