“The air hung heavy with the scent of damp earth and something metallic, a tang that made Eldrin’s nose twitch. His oil lamp sputtered, casting flickering shadows across the rough-hewn tunnel walls. Each creak of his boots on the uneven floor echoed back at him, a symphony of solitude in the inky blackness. He pressed on, pickaxe clutched tight, his eyes straining to pierce the gloom for any glint of the precious cerulean ore he sought. Unseen eyes, however, watched his every move from the inky depths above, a low rumble vibrating in Eldrin’s chest even as he remained blissfully unaware.”
Spoilers Ahead.
Last Sunday we played a one-shot D&D campaign from Rune Foundry called Tremor in the Yawning Canyons and it was something, to say the least. It was my group’s first time fully roleplaying their characters and it was a blast, there’s nothing better than a Western setting to bring out the full accents.

Tremor in the Yawning Canyons was a short but enjoyable one-shot filled with sand, jewels, caves, and monsters. The session consisted of some roleplaying for the players to figure out what the initial issue was followed by some dungeon crawling and a short but difficult boss fight.
However in my opinion this module worked better as a setting guide rather than a one-shot as the story leaves a lot to be desired and needs the DM’s support to make transitions between scenes smooth and entertaining. The monsters were perfect for the cave setting being able to blend in with the environment and move efficiently through the dirt left the players in suspense and surprise many times.
This module offers a straightforward path to the conclusion. However, a resourceful DM can enhance replayability by adding details to the environment, like hidden pathways or environmental hazards. Additionally, altering monster behavior (e.g., allowing them to be lured out) or providing clues to trap them offers players more strategic options on subsequent playthroughs.
This module was placed in a western town populated but its first generation who recently struck gold by finding piles of jewels and ore. The miners having brought back their earnings did not realize that they had accidently gained the interest of a dangerous follower. Almost overnight huge sinkholes would mysteriously appear around town, damaging property and losing the hard-earned ores and jewels.
Saloons filled with magic and gunsmoke? The roar of a steam engine echoing across the dusty plains? My first foray into a western-themed RPG session sparked a creative firestorm, leaving me pondering how to seamlessly blend these contrasting elements into a cohesive world.
Strengths & Weaknesses: A Miner’s Take
While Tremor in the Yawning Canyons offers a thrilling one-shot experience, it has its unique nuggets of gold and hidden caverns of dust. Here’s a breakdown:
Strengths:
- Western Flair: The Western setting is fantastic for roleplaying shenanigans. Dust off your Stetsons and drawl your best accents, partners!
- Monstrous Ambush: The cave-dwelling creatures blend in perfectly with their environment, keeping us on our toes and adding a layer of suspense.
- The Setting: While the setting could be more flushed out, it works perfectly for the beginnings of a world-building journey.
Weaknesses:
- Story’s the Saloon Scrapper: The core story could use some polish. A resourceful DM can definitely improve the flow and transitions between scenes.
- One-Shot Trail: The module offers a clear path to the conclusion. For those craving high replayability, a DM can add environmental details, hidden passages, or alter monster behavior to create a more dynamic experience.
While Tremor in the Yawning Canyons doesn’t require veteran players, some familiarity with D&D’s rules would be beneficial. Newer players might find the combat system a bit clunky at first. An experienced DM can definitely help navigate the mechanics and keep the action flowing.
Overall, Tremor in the Yawning Canyons offers a decent foundation for a rootin’ tootin’ good time, especially for players who enjoy a good dose of dungeon crawling. With a little extra DM TLC, this one-shot can be a real gem. For D&D enthusiasts seeking a creative springboard for their own western-themed adventures, this module is definitely worth saddling up for!
