Welcome to Crown of the Oathbreaker!
>>> Pre-orders are available at Elderbrain.com <<<
Crown of the Oathbreaker is a D&D 5e compatible dark adventure campaign taking characters from levels 5 to 13. The story is set in multi-layered sandbox realms, in which the players 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 cursed Crown of Azennar
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.
The adventure is partially set in Aglarion, a blossoming kingdom where all intelligent races are part of society and live in tolerance. This means that players can choose to play exotic monstrous races and still function effectively throughout the adventure.

Caress of the Elderbrain
Based on the survey results, Crown of the Oathbreaker is a mix between sandbox and classic storylines, with a healthy blend of combat and non-combat encounters for all types of gameplay. It also combines elements of both high and dark fantasy, resulting in a singular style. Our approach was to come up with unique twists on classic features for every game aspect that was covered in the survey.
Here are some of the major pillars of the adventure, as decided by the voting:

We are old-time friends who grew up together and have played D&D and various other RPGs together for the past 30 or so years. We have always wanted to create shiny RPG products, which we can call our own, so we launched the Elderbrain.com site and have recently released our first D&D product, “Year of Rogue Dragons”, a 100-page adventure module for evil dragon characters set in the Forgotten Realms, which quickly became a platinum seller on DMsGuild.

It was an amazing experience to hold our own printed hardcover adventure module in our hands. The pdf version was purchased by over 1500 like-minded fans, who gave feedback, support, and so much love.
We didn’t want to stop there. So we rolled up our sleeves to create this project, and we hope you will share our excitement!

The total budget is planned to be allocated to cover illustrations and designs, creating soundscapes, and of course those unfortunate taxes and fees. We do all the writing, which we enjoy doing a lot. Of course, we wouldn't mind making some money on the project if the campaign blew up, but as illustration costs are quite high, we expect that our main reward will be the realization of the product, which is a fantastic result for us in itself.
Based on our experience with our first module, and keeping in mind that Crown of the Oathbreaker is a more ambitious project and several times longer, we expect to finish the core product by the end of 2021. The edited pdf version of the product should be available by December. The printing takes two additional months and it will probably take another month for the freight company to deliver our products to our US warehouse from the manufacturer. This means that the hardcover version and the booster cards will be available probably by March-April 2022.

Delivery of digital products
All digital products will be sent via email.
Delivery of physical products
Printing costs are not included in any of the listed perks but will have to be paid directly at Elderbrain.com when ordering your physical products (book and/or cards) with the discount code in the value of your pledge, which we will send you via email.
We charge printing costs later because we started out by offering a DriveThruRPG print-on-demand solution to deliver the physical products but we realized that we can achieve a lower production cost and better quality by doing everything ourselves. With this, we would cut the price of the now almost 600-page book to one-third of its previous price. We have researched the best manufacturer, freight company, and fulfillment service provider we could find to accomplish this.
We expect the module to be about 550-600 pages long and we will prepare the print files for the 8.5” x 11” large print format. The hardcover book will be sewn bound and printed on 128 gsm paper. The printing costs of the final hardcover book will be +$25 and it will be +$12 for the two booster card decks (packed in a neat combo box). These are the extra costs that you will have to pay for the physical products above the value of your pledge.

Shipping costs are also not included in any of the listed prices, they will be added to your order at Elderbrain.com when ordering your physical product.
