Hello!
April is here, which means it is time for a proper update on where things stand with the ThunderCats 5.5e book.
The good news is that the writing and editing are complete for both books. The core book and the adventure book are fully prepared and in the final layout stage.
The only thing holding us back is approval from the licensor. Until we receive the green light, we are unable to move forward with the final steps. We hope this won't take too long and we'll be sure to let you know once we've got the go-ahead to finish up!
While we wait, we want to give you a taste of what is coming by sharing the layout drafts for the adventures! (Layout not yet final and subject to change)
Writing and layout still pending approval

*** Quick note on delivery times
We have previously shared that we added dice and a new book product to the project based on consistent requests from backers. As we communicated in several updates, these additions moved the delivery date back by a few months, pending licensor approvals.
Please note that we are unable to change the delivery dates on individual pledges once they have been made. Consequently, the dates listed on the pledge page were superseded by the updates provided during the campaign.
We remain committed to providing regular progress reports to keep you informed at every stage. We are currently on track to meet the revised deadlines within the coming weeks.
Next Steps
The next steps involve opening the pledge manager to collect shipping details and final numbers. We will open the manager on Backerkit next Friday, April 10th, and it will remain open until the physical goods are sent to print.
By that time, we expect to have all files prepared, approved, and ready for print. Once we hit the "print" button, we will be one step closer to completing this project.
For all the Snarf lovers out there: once the files are finalized and licensor approved, we will release the PDFs to all backers who pledged for them. This way, you can enjoy the Thundercats content while you wait for your physical goods to arrive.
Additionally, for those familiar with Lynnvander’s previous RPG work, we are sending all outstanding books to print and shipping them together near the end of this month. This includes Evil Dead 2 and Imaria: Pillars of Power.
If you are looking for more D&D 5.5e compatible products, please check out the "Imaria: Beyond the Veil" project during the final days of its "last chance to back" campaign.
Please keep in mind that all Lynnvander designs are created with cross-world mechanical compatibility in mind; in fact, many of the mechanics in Thundercats were inspired by the foundations of Imaria.

Thunder, thunder, thunder!
As February comes to a close, we are entering the final stretch of preparing both the core book and the adventure book for you all. We’ve been hard at work assigning art for the core book and bringing the adventures together, and we are currently awaiting final approvals before moving into the finishing touches.
Adventures
The adventure book features five adventures, one for each era of the ThunderCats saga:
The Welcome Party (Exodus era). Explore the underground temple of a dangerous cult to rescue Thunderians lost after their crash on Third Earth.
Don’t Thorburn Your Bridges (ThunderCats Ho! Era). Recover and protect a unique package through gang-filled badlands to deliver it safely.
Capture The Flag (Return to Thundera Era). Infiltrate a heavily guarded spaceship to retrieve a piece of the Treasure of Thundera and liberate a friend.
Berserker Rage (League of Third Earth Era). Defend a peaceful village from Berserker raids, then carry the fight to their warship to reclaim the stolen plunder and restore it to the people of Third Earth.
Mumm-Ra Must Die! (ThunderGuard Era). Delve into the Onyx Pyramid on New Thundera and end Mumm-Ra’s threat once and for all.
Release Plans
Our goal is to have everything ready for print by the end of March. PDFs will be released around the same time so backers can begin exploring Third Earth as soon as possible. If all goes according to plan, physical books should arrive in your hands this summer.
We truly appreciate your support and patience as we’ve worked through the production and approval process. We are incredibly proud of what we’ve created and cannot wait for you to experience it yourselves!
