In that case that means there’s plenty of material out there for you to use in your game already and you probably don’t need this.
RPGs are my full time work. I unfortunately can’t afford to give everything away for free (though there are free versions of many of my other books available). This is also in a bundle with 8 other games right now, and giving it away for free would devalue that bundle which impacts more people than just me. There’s also an extensive preview PDF available for free that contains a large chunk of the adventure.
If you don’t think £5 is worth it for a fully-illustrated 48 page adventure that’s fine. Thanks for your interest anyway.
