From Introduction:
This bestiary is for storytellers and worldbuilders. If you have ever thought about running a DUNGEONS & DRAGONS game using my SW5e conversion for your friends, either a single night's adventure or a long-running campaign, this book contains page after page of inspiration. It's your one-stop shop for creatures both malevolent and benign.
Some of the creatures that inhabit the worlds of Star Wars have origins rooted in real-world mythology and fantasy literature. Other creatures are Star Wars originals. The monsters in this book have been culled from all multitude. Herein you'll discover classic critters such as the rancor and the dewback next to more recent creations such as the shyrack and the porg. Common beasts mingle with the weird, the terrifying, and the ridiculous. In collecting monsters from the Star Wars mythos, I’ve endeavored to reflect the multifaceted nature of the game. Star Wars monsters come in all shapes and sizes, with stories that not only thrill us but also make us smile.
If you're an experienced Dungeon Master (DM) and have run traditional 5e games, nothing in this book should surprise you. For the most part, these are how I interpret the creatures of Star Wars, with a few of my own twists. Naturally, you can do with these monsters what you will. Nothing I say here is intended to curtail your creativity.
