Welcome to The Bestiary of Equestria!
Within the book lies a wealth of information about the fantastical creatures and characters of Equestria! For use with Tails of Equestria, this bestiary will help you tell fantastic adventure stories and fill the world with all sorts of beasts and monsters.

Some of these creatures are beastly, some are unique characters, and some are races that players may want to pick when creating their character.
Included in The Bestiary of Equestria are rules for six new playable races, allowing for players to pick the following non-pony characters:
Fearsome fire-breathing Dragons.
Curious and cunning Diamond Dogs.
Wondrously powerful Changelings.
Wise, ancient Crystal Ponies.
CREATURES OF EQUESTRIA
From adorable to terrifying, the bestiary contains details and stats for all sorts of creatures. This will add a huge amount of depth and variety to the types of encounters the players will face.
As well as monsters, you’ll find details on the friendly, familiar faces of Friendship is Magic. From Big Mac to DJ Pon-3, Scootaloo to Flurry Heart, and many more!
NEW TALENTS AND QUIRKS
Lots of new creatures means plenty of new powers, magic, and special abilities. The unique and often dangerous creatures of Equestria are equipped with many Talents and Quirks, which are detailed in the bestiary. Some of these new Talents can even be gained by Pony Characters when they level up!
