Crown of the Oathbreaker is a 916-page D&D 5e adventure module and a campaign setting with player options. It features scores of new monsters, encounter maps, subclasses, feats, spells, and magic items. 

The dark fantasy sandbox adventure incorporates over 40 dungeon maps and three regional maps with over 100 locations on each, taking characters from 1st to 15th level through a cursed kingdom to the Feyrealm. 

  • 3 LARGE SANDBOX AND 40+ DUNGEON MAPS
  • 200+ ILLUSTRATED NPCS
  • 30+ NEW MAGIC ITEMS
  • 80+ NEW MONSTERS AND TEMPLATES
  • 30+ NEW SUBCLASSES
  • 40+ NEW SPELLS AND FEATS 

The book is based on the feedback of over 2000 D&D fans whose votes on their preferences gave the backbone of the adventure and the campaign setting. The community influenced the fine details of the story and the setting through Elderbrain’s Discord server. Crown of the Oathbreaker also includes over 200 NPCs, their locations, and portraits based on the actual photos of members of the Elderbrain community.  

The story is set in the Kingdom of Aglarion, where the characters will uncover dark secrets from the past of a royal family after the fall of a blessed era and break a curse that plagues the kingdom.

The players will have to explore lands ravaged by the curse and travel to the Feyrealm, the Shadowrealm, and even Hell, where they will face hard moral dilemmas before saving the crown from the dreadful effects of an otherwise inevitable pact. A sinister bargain has caused suffering for the people of the land and has created a mad witch-knight hungering for revenge.

We suggest downloading the free Elderbrain Soundscapes app that contains over a dozen dynamically generated, non-repetitive background ambiances for many of the locations found in the adventure.

Chapter 1 of the adventure is available as a free download. Defeat the cultists at the Old Grinder, take part in the King's Games and the Battle of the Champions, and watch history unfold.

Crown of the Oathbreaker

Great delivery, well packed, arrived in pristine condition. From what I have read so far this is a classic and truly epic adventure, lovingly crafted and written, in a rich well-realised world, and absolutely bursting with gorgeous artwork if you like that sort of thing.
My one and only criticism is that at over 900 pages the book weighs more than a cinder block. Portable it isn't, so either invest in a pdf and stick it on a tablet, plan to invite the players to your place so you don't have to carry it anywhere, or fire up the VTT! Really, it's a great game but heavier than the Encylopedia Brittanica. All 26 volumes. ;-)

Exquisite, Superb, and Magnificent

I have been partaking in rpg's now for over 50 years and this particular monstrosity of a module is simply one of the best ever released in 2024. The adventure is beautifully structured and supported with colorful maps, diagrams, and pictures. This module is very rich in lore and will open the door to any other adventures introduced throughout the campaign. The antagonists are placed very wisely and will challenge any well versed group of adventurers. The added NPC's of those fine folk who contributed to its successful KS is nothing but a plus. Stunning in size and overall a true must have by any serious DM. Elderbrain hit a homerun with this module.

Holy Super Cow!

Dudes and Dudettes... When I got this book, I nearly busted a nut. I could only imagine the time and effort that went in to making something of this magnitude. Now I just need to find some buddies to play the module with.

The best campaign since Ravenloft

I have read a lot of roleplaying modules, this is hands down one of the best I have ever read and played. I am currently playing through CotO and am 66 sessions in, with easily another 66 to go. I love the depth and care that has been put into this campaign module, and its just so unique and different. At the rate we play and Elderbrain turns out modules, i'll be playing their games for decades to come.
