3 months ago – Wed, May 20, 2026 at 11:35:53 AM

Hi all,

We were delighted to include a nice number of Norse nasties in the original Sea Monsters bestiary, including the bunyip, draugr, fjord linnorm, giant squid, great white whale, ocean giant, sea serpent, selkie, storm hag, and, of course, the Midgard Serpent! Those guys need their bestial buddies, though, so we wanted to remind you that the Nordic Monster Kickstarter for Pathfinder Second Edition, Pathfinder First Edition, D&D 5.5E, and Tales of the Valiant ends in 30 HOURS! Get nearly 90 incredible creatures from Norse mythology and Scandinavian sagas like jotuns, valkyries, einherji, sleipnir, and epic foes like Níðhöggr, Fenris Wolf, Grendel, and the Yule Cat! Bundle with our entire Legendary Bestiaries line of monsters from real-world folklore of Asia, Africa, Latin America, & the Mediterranean as well as fantasy, horror, sci-fi, and more! Get PDF, print, or VTT with VTT Roll20, Foundry, Fantasy Grounds, and Shard! Best of all, fulfillment starts in June

Every monster in the artwork below was made possible by our backers, so pledge today and help us reach 1,000 and even more stretch goals before it all ends THURSDAY NIGHT at 6:00 PM Pacific!

Expanding VTT Options for Sea Monsters and SWARMS!!!
over 1 year ago – Wed, Nov 27, 2024 at 03:12:50 PM

Hi there and thanks for your fantastic support of Sea Monsters! We wanted to share the good news that even as we've expanded our original Sea Monsters bestiary for more systems--including Tales of the Valiant/Black Flag, Pathfinder RPG, and Pathfinder Second Edition--we are likewise expanding VTT options for all of them! 

We've just completed the Roll20 VTT module for Sea Monsters (PF2) and have reassigned work on the Foundry VTT module for it as well. We hope to have that ready by late December and whatever your favorite system, we hope you enjoy these terrific VTT options! Let us know if there are specific VTT products you'd love to see from us! 

At the same time, while we look back at this great project, we also look forward to new monster books all the time, and we just recently launched our latest QUICK-starter for Legendary Bestiary: SWARMS and we would love to invite you to check it out! 

Get classic swarms like vampire bats, scarlet spiders, and horribulous rat swarms alongside exotic monsters like living wildfire, dead ink swarms, fairy rings, hexagnomes, neutron starlings, finger-crushing lobsters, and the floofy kitten swarm!

As you can see, this project is available for 5E, Pathfinder 1E and 2E, and for Black Flag RPG/Tales of the Valiant! You also can fill in any of our other marvelous monster books missing from your collection from Asian Monsters to the Faerie Bestiary! We hope you'll check it out and consider adding Legendary Bestiary: SWARMS to your monster menu, and share it with any of your 5E friends, Black Flag buddies, or Pathfinder players at the link right here!

Again, thanks so much and have a Legendary finish to 2024!

And as we keep cranking through our shipments, the train keeps rolling as the Mother of Monsters Quickstarter is now LIVE, bringing you 200 pages of amazing adventure plus new class options, races, monsters, magic items, deities, world lore, and more for a campaign inspired by Greek mythology and set in the Kagari Islands!

The Shippification has Begun!
almost 5 years ago – Sun, Oct 17, 2021 at 11:44:31 PM

We got back from our camping trip on Friday and on Friday evening the truck finally delivered our books from the port! We did a small test batch of packages that went out on Saturday, and we've got a carload more ready to go out to you this week. I'm flying out again early tomorrow morning and will be gone until Friday, but my son will be taking this load to the post office to start heading your way! 

This first load is mostly from the Mythos Monsters Kickstarter, but we are sending them out in groups of backers who are getting the same combination of items, which makes packing and labeling go so much faster. Among these are backers who are getting Sea Monsters and Mythos Monsters (with no other extra books), which was 84 of you! Happy reading to all, and we'll get more loads sent out next week when I return!
