From publisher blurb:
You've fought basilisks, dragons, manticores, and wyverns.. but have you really?
History buff and accomplished game designer Michael Surbrook welcomes you to rediscover all the incredible monsters, beasts, and strange beings of the Middle Ages in a way you've never encountered them before. With deep research and Pathfinder 2e mechanics that eschew "standard gaming" for "what they were believed to be like," you can introduce creatures for your campaign’s player characters to encounter that are almost certainly not what they were expecting.
From a short history of medieval beasts and monsters (and a look at the geographical world through European Middle Age eyes) to a thorough presentation of both magical monsters and mundane creatures, Here Be Dragons is a monster manual for the history fan in all of us. It's also a powerful tool for any Game Master looking to make the Old World all-new for players who think they know everything about the monsters they fight.
