Standalone Adventures
One-Shots
Four standalone adventures set across the world of Scalethorn. Each can be played independently or woven into the main campaign. Each leaves a mark.
Safety Tools
All Scalethorn one-shots use Lines & Veils / Script Change. Before any session, agree on what is off-limits and what needs a softer approach. Adjust tone to your table. This is always the first thing on the agenda.
— Selen Vire, Observer
Set long before the events of the main campaign, The First Scar tells the story of the very first meteor to fall from the broken sky. A strange light was seen in the heavens. Then the jungle went quiet. Animals won’t go near the impact site. Plants behave wrong. The air feels thick in ways that have nothing to do with humidity.
An elderly observer who witnessed the fall asks the characters to investigate. What they find at the centre isn’t a threat — it’s a mystery. A small creature, nothing like anything native to this world, resting in a region that now responds to presence, emotion, and intent.
The characters have to decide what to do with something they don’t understand. Then they have to live with that decision.

— Tilla Cobblestone, moments before everything got worse
A group of gnome artificers have built Scalethorn’s first locomotive — a steam-powered engine fed by enchanted water vessels and magical fire. The maiden voyage runs from Strioden to Pestraval, carrying engineers, investors, and cargo. The characters are hired as guards. The journey starts smoothly.
Then the train starts accelerating. And nobody can stop it.
Someone has sabotaged both the braking system and the engine’s shutoff mechanism. The saboteur is still on board, hiding among the passengers. The players must fix the train, find the culprit, and keep everyone alive before the 9:15 to Pestraval becomes the last train anyone ever rides.
It’s a heist movie in reverse. Instead of everything going to plan, everything is going wrong, and people who don’t fully trust each other have to cooperate under pressure. The comedy comes from the situation. The danger is real.
— University Expedition Journal
An archaeological dig has been abandoned after multiple disappearances. No bodies have ever been found. Previous expeditions reported strange phenomena: echoes, time seeming to skip, voices that arrive before the mouths that spoke them.
The site was once home to scholars who studied Resonance and what it means for time. Something went wrong. The loop has worn thin enough that outsiders can finally enter — but the ruins are not quiet, and the forces at work inside do not follow ordinary rules.
To understand what happened here, the characters must piece together what came before — and decide whether the loop can be ended, and at what cost.
An archaeological dig has been abandoned after multiple disappearances. No bodies have ever been found. Previous expeditions reported strange phenomena: echoes, time seeming to skip, voices that arrive before the mouths that spoke them.
The site was once home to the Valdris Enclave — scholars who studied Resonance and its relationship to time. Centuries ago, their leader attempted to use Resonance to travel back in time and save his dying child. He failed. The ritual trapped the entire enclave in an endless loop, repeating the same stretch of time forever.
The loop has worn thin enough that outsiders can finally enter. The party explores the ruins in the present, aided by mysterious forces they don’t understand. Then they accidentally trigger the time-travel ritual — and find themselves in the past, where they realise they were the mysterious forces all along.
The characters begin already captured. Stripped of most equipment. Held in a damp stone cell beneath Threlmoor’s marshes. A disembodied voice explains the rules: fight, survive, win. The reward is power beyond measure.
What follows is a gauntlet of arena combat across four escalating rounds — but defeat doesn’t mean death. Those knocked unconscious are removed from the arena, healed, and given information. Some of it is genuine. Some is lies. Some is designed to sow paranoia and turn allies against each other.
By the final round, players hold fragments of a larger truth. What that truth means — and the choice that follows — is the real adventure.

By the final round, players hold fragments of a larger truth. This pit is not entertainment. It is a recruitment trial run by a hidden faction that has been watching, evaluating, and deciding whether you are the kind of person they can use. The choice they offer at the end is real, and its consequences follow you home.
How They Connect
Each adventure is complete in itself. No prior knowledge of Scalethorn is needed to play any of them. They can be run in any order, or used as entry points to the main campaign.
Events in the one-shots connect to the main campaign’s history. Each leaves a thread that the campaign can pull — if the characters know where to look.
Events in the one-shots connect to the main campaign’s history. The First Scar shows why Zhann’Kai is strange. The Hollow Loop reveals how temporal scars form. Each leaves a thread that the campaign can pull.
Each one-shot includes guidance for using pre-made characters or bringing your existing campaign characters. Level recommendations are listed — they exist for balance, not gatekeeping.
