From the campaign:
Like most Symbaroum books, the Monster Codex will be built in three sections. Our ambition is to produce a bestiary which is much more than a listing of new foes for the player characters to fight (or run away from). We want the creatures featured in the book to contribute to the lore of the game world, and we want them to offer different kinds of challenges to the players and their characters.
The campaign's doing well, being more than 4x funded with still 20 days left to go.
