from the introduction:
This supplement includes more than 140 creatures for your Labyrinth Lord campaign, or for any game compatible with the classics of our hobby. I won’t tell all of them are new, as you probably met some of their cousins in your earlier games, but I hope I hope you will enjoy meet them under their new clothes.
It includes some classic and giant animals, dinosaurs, undead, constructs, weird horrors, various humanoid races, from low to very high level. You will probably found some which fits well your campaign, as well as your own publications – provided you respect the terms of the license published on last pages.
