Thanks for the comment! The book doesn't use strict D&D races and classes, but rather the high-fantasy archetypes. The clasess such  along with the alignments, listed on the stat blocks" are provided to help facilitate gaming quickly. 

General races and classes such as half-elf, dwarf, wizard or a fighter are common for many high-fantasy games such as DnD, Pathfinder, GURPS Fantasy or Savage Worlds, and thus can be used universally. That's why there are no DnD or Forgotten Realms branded races such as drows or kenku - although there are dark elves and birdfolk, that could help you find the best equivalent in your setting.

Those things didn't originate with D&D and they're far from unique to it.  Even the alignment system (which in its first incarnation had only the Law-Chaos axis) was taken from Poul Anderson's novels. The race and class names have been coded to mean specific things in D&D but they were coined from archetypes that have been around a lot longer than the game has.  Pathfinder uses many of the same names BECAUSE the makers of D&D didn't create them and don't own them (and Paizo's Remaster ditched the few things that might be an issue).
