This is really cool! Narrative games in a 40k setting seem really underexplored atm and this is just what I'm looking for. I'm putting a game together with some friends as we speak. I've noticed that the character keeper spreadsheet isn't totally converted to this system, it seems to have content from Heart which hasn't been updated yet.
Hi! That's so awesome, I love to hear that! I would also love to hear how your game goes.
I've uploaded "Lex Ecclesiastica Character Keeper v2.xlsx", which you should have access to. It hides all the data-only sheets and fixes a few remaining bits of text from Heart (like the Resistances on character sheets 2-4)
