Quick Answer

Into the Würmhole is a compact, low-cost Vast Grimm adventure zine that gives you everything needed to run a one-shot session, including quick rules, pre-generated characters, a map, and random tables.

What Makes This Zine Stand Out

Into the Würmhole was the first Vast Grimm Free RPG adventure, created for the 2021 event. It's a self-contained package that lets a group jump into the grim, sci-fi horror setting without needing the full rulebook.

Because it's a zine, it's intentionally short and focused. You get a complete adventure in a small format, which makes it easy to carry and quick to prep. That's a big advantage for game masters who want a one-shot without committing to a long campaign.

The trade-off is that 'mini' means less depth. You won't find extensive lore or multiple branching plots. It's a single adventure designed to be played in one sitting, so if you're looking for a full campaign, this isn't it.

Common Questions About Into the Würmhole

Do I need the full Vast Grimm rulebook to play?

No. The zine includes Vast Grimm Quick Rules, so you have the essential mechanics to run the adventure. However, the full rulebook adds more depth and options if you want to expand beyond this one-shot.

How many players is it designed for?

The zine comes with 4 pre-generated characters, so it's set up for a group of four players. You can adjust by adding or removing characters, but the adventure is balanced around that number.

What do the random tables add?

The random tables provide unpredictable elements for encounters or events, which increases replayability. You can run the same map multiple times with different results, making the zine a good value for its price. Consider running the adventure twice with different random table rolls to get more value from the zine.

Is this suitable for new RPG players?

Yes. The quick rules and pre-generated characters lower the barrier to entry. The adventure is short, so new players can get a feel for the game without a long commitment.

How long does it take to play?

As a mini adventure, it's designed for a single session, typically 2–4 hours depending on your group's pace. The map and random tables keep the story moving without excessive railroading. Plan for a shorter session if your group is new to the system or prefers more exploration.
