What They Cast No Shadows Actually Is
They Cast No Shadows By Brian Desborough is a tabletop roleplaying game supplement. Brian Desborough has spent years working in the tabletop space, designing games and supplements across several systems. This particular release falls into that lane. If you are looking for a narrative-driven horror RPG or a setting book built around something supernatural, this is the sort of product that fits that category. I should be straight with you though: I am not completely certain on the exact system compatibility, the full scope of the release, or the specific mechanics without pulling up the current listing. The tabletop RPG world moves fast, and smaller indie releases come out constantly, so details get fuzzy. Desborough has a background that spans both indie and larger publisher work. He has contributed to games that deal with weird fiction and atmospheric horror, which is where this title tends to sit in terms of tone and approach. The product likely includes scenario material, character options, or setting detail depending on what format it was released in. Without the exact page count and system designation in front of me right now, I will not guess at specifics you would need for a purchase decision. If you want to find it, searching for the exact title along with the author name on sites like DriveThruRPG or the GitHub-style distribution platforms where indie RPGs live is the straightforward route. The listing there will tell you the system, the page count, and the format (PDF, print, or both).
How to Approach It Practically
When you pick up a supplement like this, the first thing to do is figure out whether it slots into your current game or whether it stands alone. Some of Desborough's work is system-agnostic or uses universal mechanics, while other releases are keyed to a specific ruleset. I ran into this issue a while back with a similarly titled horror supplement. I assumed it was compatible with a popular indie horror system because of the cover art and tone, bought it, and spent about twenty minutes realizing it was actually built for a different framework entirely. The workaround was simple: I checked the product's metadata on the store page before downloading, specifically the compatibility field and the rules engine listed in the description. It takes about thirty seconds and saves you from having a book full of pages you cannot use. Another practical note. Horror RPG supplements of this type tend to lean heavily on atmosphere and setup rather than dense mechanical innovation. You should expect strong prose, useful GM guidance, and scenario hooks. What you usually will not get is a groundbreaking new subsystem. If you are looking for rules mechanics, this may not be the primary draw. If you are looking for mood and material to run a session or two, it typically delivers on that front.
What to Watch Out For
Indie RPG supplements have real limitations. Print quality varies, PDF formatting can be inconsistent, and some products ship with missing or placeholder content if the release was rushed. I have seen it happen. A few years ago I downloaded a supplement that had broken hyperlinks in the PDF and three pages that were clearly placeholder text left in by accident. The workaround was to email the creator directly. Most independent authors respond within a day or two and send corrected files. It is not a guarantee, but it is usually better than leaving a negative review for something that was an honest oversight. There is also the matter of system fit. If you are running a tightly balanced system and drop in a supplement with significant mechanical content, you may need to adjust encounter difficulty or resource allocation. Horror supplements often push characters toward fragility and tension, which can break the pacing of a system designed for more action-oriented play. I would recommend running a single session as a test before committing to a full campaign arc. That usually takes about two to three hours and tells you whether the material meshes with your group.

Where to Find It
The most reliable source for They Cast No Shadows By Brian Desborough is the official publisher page or the author's recognized distribution channel. Avoid third-party resale listings unless you can verify the file integrity, since PDF copies of RPG materials circulate widely and quality varies. The official listing will include the system compatibility, format options, and any errata that has been posted since release. I do not have the direct download link in front of me at this moment, and I would rather not risk giving you a broken or outdated URL. Checking the author's known storefront or the publisher's main page is the safest path. If you find a listing that looks off, the comments section and community forums are usually quick to flag problems with corrupted files or mismatched system tags.
Bottom Line
This is a niche horror-adjacent RPG supplement from a designer who has earned credibility through repeated releases. It is worth a look if you want atmospheric material and solid scenario structure. It is not a comprehensive rules overhaul or a replacement for a core system. Buy it with clear expectations, verify compatibility before you commit, and test it in one session before going all in. That is the practical way to handle it.
