More Monsters! Now: Divine Intervention?
5 months ago – Fri, May 01, 2026 at 03:35:29 PM



Hello, backers—

We’re in Overtime Mode, but the campaign is still on fire. You’ve unlocked the big expansion to the Creatures of Vocurro bestiary!

This book is getting a lot meatier, with a bunch of additional creatures being given the expanded treatment that includes options, alternate versions, lots of lore and supporting information, and more. This approach really helps you breathe life into your Jewel encounters, and makes it easy to use these creatures in other adventures.


This expands Creatures of Vocurro—whether you get it as a component of the boxed set or as an add-on.

In addition, we’re adding another card to your XP card collection—it’s a free bonus reward we give every backer, no matter their pledge level, as a thank-you for helping to unlock the goal.

Here’s the card you chose:


Overtime Mode—and More Stretch Goals?

We’re in Overtime Mode, so as long as pledges keep coming in, the campaign stays open. All Mega Dungeon Month campaigns will stay live until all of them simultaneously go 10 minutes without a new pledge.

How long will that be? For our past campaigns, that’s been anywhere from a few hours to almost two whole days. Our last campaign drew nearly 150 backers in Overtime Mode!

So as long as the campaign keeps rolling, why not keep the stretch goals going?

Still Time for Something Really Cool!

Here’s a really unique aspect to the Jewel in the Sky adventure—the influence of two powerful and enigmatic entities: Dalyn, the Optimist, and Korana, the Pessimist. Some on Vocurro worship them as gods, but perhaps their true nature hasn’t been fully revealed.

Dalyn and Korana are subtle but active participants in your exploration of Vocurro, influencing the adventure through events triggered by the patterns of your players’ die rolls. You don’t need anything special to track this process, but we’re including the Twin Clocks Timer in the boxed set to make it a bit easier and to amplify the tension this can add to the game.

The Twin Clocks Timer, as we’re currently planning it, is pretty cool—but we think it could be even cooler. Take a look at this:


We’d like to give it a base that angles it away from the players’ prying eyes—or that can be used to hide it like a mini GM screen. We’ll also add deluxe features such as spot varnish or foil stamping, and a cool custom die-cut design, to give the Twin Clocks Timer the premium feel it deserves.

Help us reach 2550 backers before the end of Overtime Mode, and we’ll upgrade the Twin Clocks Timer included in the box to a truly premium component!

Backers are coming in very quickly at this point. This goal is a stretch, but based on our long experience with crowdfunding, we think it’s totally doable—if you keep spreading the word!

Choose Another XP Card

Why not have another quick poll? These are two cards that didn’t win their votes—but were still pretty popular. Let’s give them a second chance. Which should we include as a free bonus reward if you unlock the Twin Clocks Timer upgrade?


Did You See the New Art?

In case you missed it: we dropped a bunch of new art in an earlier update today. Check it out! And please keep spreading the word. There are thousands of gamers out there who haven’t even heard about this campaign—and will be sad to learn they missed it. You can help them find it before it’s too late!

Thanks for your support!

Jewel Is in Overtime Mode!
5 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!
5 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?
5 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!
