From the publisher's website: Welcome to the first of what will be many such volumes from the library of Xandegar’s Adventure Realm. This one as by no doubt you have guessed is based around the ancient Greeks. Here-in you will find a collection of OGL creatures/monsters that are based on REAL Greek mythology. From the classic Minotaur and Hydra to the lesser known White Eagle of Zeus. From the simple Striges to the down-right terrifying Charon, the Boatman of the River Styx!!
