First off, GNU Terry Pratchett.
Second off, I am really grateful for the thoughtful feedback you gave me so I will try my best to do the same in turn :)
Theme: The unmortals is a strong idea and feels just on the right side of weird for a traditional fantasy game. I do wonder if making the module system agnostic/easily adaptable has resulted in a slightly more generic setting.
Writing: The writing is clear and readable. I respect the choice to provide an in-depth rationale instead of providing detailed individualised keys, allowing GMs to have a better idea of how to fill in the blanks. However, I do think that in some cases you could have your cake and eat it too. A few things could be worded just a little more evocatively to help GMs down the right path, without impacting word count. The Sword of St Tomaz is a good example. Cool name, but how important is it for the GM to know which saint it is attributed to? At the moment it’s a piece of lore that doesn’t really point anywhere and is hard to come up with a concept for. “The Sword of Petrification”, for example, is perhaps more gamey-sounding but easier for a GM to rustle up an item description for.
Layout: Clear, well sized font. Good line spacing makes such a difference to readability. No notes.
Art: I love your art! The illustration of Death(or an Unmortal?) is really good. Personally, as a GM I wouldn’t be able to get much out of the owl illustration, although it looks nice. I think I would have preferred it if the owl was omitted and the cartography was in turn expanded and made more informative.
Playability: This module isn’t your typical pick-up-and-play. Locations like the fort and lighthouse are calling out to be keyed beforehand which would be take a fair amount of prep time. However, I realise that this is a feature not a bug. I’d be super interested to see more of the material you used when running it in your campaign.
I really like your Rumours mechanic. The customised reaction table combined with encounters is excellent too. Loads of emergent situations could come from those alone.
If I was running this I would 100% introduce an alternative to killing the witch. Maybe something to do with the sword.
Overall this is a nice little campaign frame. It is similar to Andrew Walter’s Fronds of Benevolence in that depending on the GM’s tastes and style, it could last a gaming group just a few sessions or be the basis of an entire longterm campaign. An excellent effort in 4 pages!
