Hi Justin. I plan to start a campaign in Moth-Light soon (January 2021, maybe later). I would like to ask you about possible Roll20 character (and Pact) sheet. It would really help my technical preparations

Hi, Mansfield! Firstly, thank you so much for running the game! Know that I’m planning a big update shortly (before the end of the year, maybe even in the next week). 

In that time I’ll be updating the google sheets and looking into making sheets for the Role App, but I don’t have much experience making sheets for Roll 20. It’s ok my horizon but likely something that will happen closer to the Kickstarter unless an enterprising fan lends me a hand. I’ll ask around and see how plausible it would be to whip something together. ✨

While I can't offer a roll20 template at the moment (it takes a LOT of time and effort to make a good roll 20 template) I hope you will enjoy the new format for my google sheets, recently updated, found in the demo section. I'm also working on a template for the Role App, if that is of interest! (https://app.playrole.com/)

For your perusal, here is a direct link to the Promise pact g-sheets: https://docs.google.com/spreadsheets/d/1DeA_gY1NnS7e_sXb7iKr29rqQAEYwn8yM8YYH5LY..

Thank you! :)

Hi Justin. Pag. 70, the RUIN explaination mentions "ruin" again, while the other skill (as in BitD) always suggest a different skill better suited for a not-so-ruin action.


I'll correct it! If anyone has editing comments, happy to receive them via my email (listed in the first few pages of the game doc and on my designer page).

I did a looong email, giving you all the feedback I can. I'd just to be sure you received it, 'cause I had no ping back. Thanks for the attention.


Yes! I received your email. I’m currently in the middle of a rules revision and overhaul that may address some of your thoughts. Sorry for not getting back sooner ✨


Hi, Andrea! I haven’t forgotten about you. This latest update might address some of the thoughts you had posed to me. I’ll address the rest in an email ✨


This game does some really clever new things with the Forged in the Dark model that I hope ripple out and inspire other designers the way they have me! The setting is really rich and permeates through the rules and text in a way that is really masterful (even as the writer says setting and lore will be developed further!). Similarly, the design and layout are on point and look very pro, especially for something that is still in development. 

Super impressed by this whole game and eager to see how it continues to grow.
