Latest Updates from Our Project:

Jewel Is in Overtime Mode!
about 2 months ago – Fri, May 01, 2026 at 02:10:23 PM



Hello, backers—

Mega Dungeon Month has reached its scheduled closing time—but Jewel in the Sky still going!

We’re in what’s called Overtime Mode: as long as new pledges keep coming in—for any Mega Dungeon Month campaign—Jewel in the Sky remains open. It ends when only when Mega Dungeon Month hits a 10-minute stretch with no new pledges to any campaign.

How Long Will It Last?

Nobody knows!

Could be just an hour or two. Could be much longer. In our last campaign, we had nearly 150 pledges in Overtime Mode!

That’s not a rounding error—it’s a big deal. And it means we can still unlock stretch goals—in fact, you've aaaalmost unlocked the Creatures of Vocurro bestiary upgrade, and if that happens soon maybe we can even go for another one!

So please go out there, share this campaign, and help spread the word!

Tell people in these threads that Overtime Mode is rolling RIGHT NOW.


You can also find loads of sharable posts and images on MCG’s social media accounts:


Spread the word, and let’s hit more stretch goals!

Big Art Drop! Early Access! It’s the LAST DAY!
about 2 months ago – Fri, May 01, 2026 at 08:19:56 AM

Hello, backers—

It’s the final day—often the second-most exciting of a campaign (after the launch day). Let’s kick it off with a bunch of new art! But first:

Do You Want Early Access?

Would you like early access to Jewel in the Sky? Would you like to connect with a welcoming, friendly, helpful community of Cypher gamers? You can get both by joining the Cypher Unlimited discord, the fan-run community for MCG’s games!


If you are a backer of this campaign, and also a member of the CU, we’ll give you early access to Jewel in the Sky. You’ll get pre-release files well ahead of the adventure’s release (in addition to your regular rewards, of course). The CU is a fantastic community where thousands of fans congregate to discuss, share, find games, and more. We’d love to have you join us there!

Now Let’s See Some New Art!

As promised, we have a bunch of new art to share with you. All of this art depicts actual scenes and locales in the Jewel in the Sky adventure—in fact, that’s true of every piece of art we’ve shown you in this campaign. How cool is it going to be to explore these mysterious and enticing places?

We’ve added this art to the collection of files you can peruse and share to help spread the word about Jewel in the Sky!



Thanks for your support!

Cloth Map Unlocked! Who Wants More Monsters?
about 2 months ago – Thu, Apr 30, 2026 at 01:41:46 PM



Hello, backers—

You’ve unlocked the cloth map!

Things move fast in the final few days, and it was just yesterday afternoon that you unlocked our previous goal. The pace is only increasing, and we have more cool goals we’d love to hit. We still need your help—keep the buzz going and we’ll continue to soar through more goals before it’s over!

The cloth map—so beautiful you’ll want to hang it on your wall (but maybe too spoiler-filled to put it where your players will see it)—is a great addition to this singular boxed adventure. It's also now available as an add-on!

But that’s not all: we’re also giving every backer a free bonus deck of exclusive Jewel in the Sky XP cards. It was really close, but, by a whisker, you voted to add this design to the collection:


Stretch Goal: Let’s Expand the Bestiary

Early in this campaign, you added the Creatures of Vocurro bestiary to the boxed set. (We’ve since made it available as an add-on, too.) If you’ve ever flipped through the Cypher System Bestiary, you know how deeply we like to imagine the creatures with which we populate our worlds. Stat blocks and basic info, including illustrations, are included in the Jewel in the Sky book. But the bestiary lets us layer in more detail, optional abilities and appearances, useful details about monster lairs, their relationships with other creatures, and lots of other topics. This gives you, as the GM, so much to sink your teeth into—and lots of ways to bring these creatures to other adventures with depth and interest.

Although each creature in the bestiary gets a two-page spread, the book is still pretty modest. But Monte keeps designing, and his dungeon keeps filling up with more creatures. What if more of them were given the full bestiary treatment? What if we nearly doubled the size of this book?

Get us to 2450 backers, and we’ll dramatically increase the size of the
Creatures of Vocurro bestiary! This increase in size applies to both the boxed set and the add-on. 

And Another XP Card!

As always, when you unlock this goal, we’ll add a bonus reward for every backer, no matter your pledge level. Which XP card should we add to the collection this time?


It’s Down to YOU!

Believe it or not, this isn’t the final goal we want to unlock. We’ve run a LOT of crowdfunding campaigns, and we know from experience we can still hit another couple—with your help. Keep the buzz going—share social media posts, comment on Reddit, and tell every gamer you know about Jewel in the Sky!


You can do it—we believe in you!

Thanks for your support!

AMA on BackerKit now on YouTube
about 2 months ago – Thu, Apr 30, 2026 at 10:43:34 AM

Hey folks

In case you missed yesterday's chat with Monte, Charles and Liv, its up on YouTube here!

We're close to the end of the campaign and more things we'd like to fund! Help us let new folks know about Jewel in the Sky in the last few hours!



Cyphers and Cards Maxxed!
about 2 months ago – Wed, Apr 29, 2026 at 12:39:07 PM



Hello, backers—

You’ve unlocked yet another stretch goal. Monte’s adding more cyphers to Jewel in the Sky, and we’re increasing the card count to 100. Literally a hundred cards in this box!

We’re down to the final few days of this campaign, and we have quite a few cool stretch goals we’d love to unlock—in fact, we’ve saved some of the best for last. We’ll get to the next one, but first:

Help Keep the Buzz Going!

People are talking about Jewel in the Sky, and that’s really helping us reach new backers. Here are some of the conversations currently ongoing out in the gamersphere—if you have a minute, pop in and upvote or comment on these threads. That keeps them going, and helps them reach new gamers:


The more people talk on these threads, the more new gamers we reach. There are still thousands and thousands of gamers who haven’t even heard about Jewel in the Sky or Mega Dungeon Month, or who have thought about backing but haven’t quite done it yet.

It only takes a few minutes to help reach hundreds of gamers!

Your Bonus XP Card

As always, we have a free bonus reward for every backer to thank you for unlocking the latest stretch goal. We asked you to vote for your next XP card to add to the collection, and you chose this one:


Stretch Goal: Let’s Add Some Luxury to the Box

The Jewel in the Sky boxed set already contains (thanks to a stretch goal you unlocked earlier in the campaign) not one but two useful poster maps.

But what’s more elegant and attractive than a big paper map? A gorgeous cloth map, that’s what! And we’d like to add one to the box! This classy addition will feature the main dungeon map, setting it apart from the poster maps (which cover Vocurro as a whole). It'll be so beautiful you can hang it on your wall.

Get us to 2200 backers, and we’ll include a cloth version of the primary
Jewel in the Sky map in the box!



We’re seeing the pace pick up quickly, as is usually the case in the final week of a campaign. You can make this happen—faster than you think!—and move on to several more goals before it’s all over. If you help spread the word!

Let’s Pick Another XP Card

As we do each time, when we unlock this goal we’ll include another XP card as a free bonus reward for every backer—a thank-you for helping to get the word out. Which one should we make next?


Remember, we have just a few days left. Your help will unlock even more stretch goals!
