Latest Updates from Our Project:

Australia + Asia Books ALL in the mail + Some GREAT NEWS!
7 months ago – Wed, May 09, 2018 at 09:55:08 PM


The US region orders went out the door over a week ago, and as of today, this is also true for the Australia and Asia region orders!

If you haven't received tracking yet, you should soon! 

The European region orders should all be out the door by the end of this week.

Also - although this doesn't apply to KS backers - all the pre-orders of books from our website are going out this week as well!  (We wanted to wait until all KS orders have been mailed). 

The PDF is a bestseller on DriveThruRPG!

Also, we put the PDF live on DriveThruRPG just this week, and it's number 8 in the "bestsellers" category list!  

Pre-order campaign for DnD 5e version this Summer!

We have decided to NOT use Kickstarter for the DnD 5e version of this book. Instead, we'll have a month long pre-order campaign on our website. This will go live later this year (likely July or August, we'll know when it gets closer).

We'll launch after the book is ENTIRELY complete - you'll get the PDF download immediately when you pre-order the DnD version of the book!  

I'll be sending the files to the printer after the pre-order campaign, but you'll have the PDF version immediately. In other words, you won't have to wait over a year this time!

Also - the DnD version will include NEW art - especially for the monsters! Below are some samples!

Europe, Asia, Australia ALL at Customs!
8 months ago – Wed, Apr 25, 2018 at 07:48:03 PM

Europe, Asia, Australia all at customs

I have great news! The three shipments respectively to Europe, Asia, and Australia have all arrived in port! They are all sitting at customs, which normally should not take more than a week or so. At that point, they'll be freighted to their respective warehouses, and then fulfilled!  

We've already sent our fulfillment spreadsheets to each warehouse so they can prepare before even receiving the books. 

US orders all processed!

While not all packages have arrived - and not all tracking emails have been sent out, the US orders have been picked, packed, and are either waiting for pickup, or actually in the mail somewhere. Whatever the specific status of YOUR order in the Western Hemisphere, it is in the final stages and cannot be more than a week or so away at the most!

ALL North and South American orders in mail by end of week
8 months ago – Wed, Apr 18, 2018 at 07:43:23 PM

The book, the signed collector's edition, and the monster deck almost at your home!

Our shipper has told me that all orders for US, Canada, and S. America should be in the mail by the end of this week. 

You should be sent tracking numbers as well. 

Rest of the World Soooon

I'm trying to get a good ETA for the rest of the world - I should have that by my next update!

I know this update was short, but it's one of the best updates for this project!

New Improved Hero Labs Update!
8 months ago – Thu, Apr 12, 2018 at 06:24:52 PM

Fellow monsters,

Things are now much more clarified with Lone Wolf (developers of Hero Labs). 

First, Arthur (me) made a big mistake in confusing those who purchased Hero Labs through our pledge manager (about 84 of you), and the FREE STRETCH GOAL of having Hero Labs support for this book (which goes to any of you who have Hero Labs Classic).

Second, there was information not passed on from others on both of our teams to me, as well as to my counterpart at the Wolflair. The miscommunications are now cleared up, thankfully. 

Our book files have an ETA to go live on Hero Labs around the end of this month

If you do NOT have Hero Labs Classic, but are interested, please click here to purchase it from Wolflair.


If (or when) you have Hero Labs Classic, click here!

We need to know your exact Hero Labs Classic email for them to send you the files when they are ready (ETA end of this month). So, please take this survey, so we can send your email to Wolflair.

Also, important note - please ignore my previous request to email James and send him your email.  That was when we believed we only needed 84 emails. We need a lot more (potentially 2000, depending on how many of you have Hero Labs!). So, instead, please simply take the survey above!


Sorry for all this confusion. Please don't cast malign magics my way.

Some News regarding HeroLabs!
8 months ago – Tue, Apr 10, 2018 at 09:54:54 PM


I've been emailing the folks at Wolflair about once a week to answer some questions and get a status update (I'm very unfamiliar with the process for getting files ready and distributed - I do not have a HeroLabs account myself). 

I finally got a reply today telling me we'll need your email addresses associated with your Hero Lab Classic account.  (I wish I had known this earlier, as it may briefly delay getting you your files). 

I have downloaded the list of everyone on this project (including late backers) who ordered the HeroLabs files. I've instructed James, our support, to email everyone to confirm what their Hero Lab Classic account email is, in case it is not the same as your Kickstarter backer email.

Once I have the proper emails (or confirmation that it's the same email), I'll provide that list to HeroLabs.  I have no real sense of what happens after that - but I assume Wolflair will send everyone on that list the files. 

I'll have to follow up again, as their communication wasn't entirely clear about "what" exactly happens next. 

In any case, everything should be finalized soon!

You can help speed up this process!

James will be emailing everyone on the list. But, feel free to email him so he can simply log it into his spreadsheet:

Email James at james at petersengames dot com to either confirm that your backer email address is the same as your Hero Lab Classic email, or to tell him what that email address is.
