Dark fantasy survival, ready to play at your virtual table.

Cairn is a rules-light tabletop RPG by Yochai Gal about adventurers exploring a dangerous, mysterious forest. Characters are fragile, gear matters, and every choice counts. This system brings Cairn Second Edition to Foundry VTT, and it handles the bookkeeping so your table can focus on the story.

Pick one of the 20 backgrounds, such as Aurifex, Bonekeeper or Fungal Forager, let the dice pick one, or choose one the Warden wrote for the campaign. The creator walks you through it step by step: a name from the background's own list, attributes, starting gear, personality traits, a Bond and an Omen. Anything you leave blank is rolled for you. Already built your character on Kettlewright? Import it with one click.

Ten inventory slots, where heavy (bulky) items take two and Fatigue fills them up. Fists, claws and anything else that is part of the body cost no slot, and every character starts with their fists. Click STR, DEX or WIL to make a save. Rest, Restore and the Die of Fate are one button each. Armor adds itself up from what you wear. When a character is overloaded or panicking, the sheet shows it.

The Actions menu lets a player Whisper in character, Barter gear and coin with another player's character, open the one-page Rules Summary or the Calendar, and run the macros the Warden has put there. Drag a sack or a cart onto another sheet you own, such as your mule's, and everything inside goes with it. A companion that comes with a background, like the Raven Familiar, is dragged from its item straight onto the map.

Roll damage and apply it to the targeted token. Armor soaks what it can, HP goes first, the rest spills into STR, and the chat card offers the critical-damage save when it's due. A fall or a cave-in rolled on the spot applies the same way, and a hit on the wrong token is undone with one click. Scars, Panic, impaired and enhanced attacks, blast, Morale and Reactions are all handled. The combat tracker follows Cairn's rules: sides take turns, with no initiative roll.

• One-click generators for NPCs, hirelings, monsters, whole factions and names for places, realms and forests, all built from the rulebook's own tables.
• A calendar in the Vald reckoning of the Warden's Guide: watches, seasons, the Reclamation, and notes on any day, starting with the setting's holidays. The Warden sets the time and shows it to everyone.
• Journeys: a shared travel window that runs the wilderness watch by watch. It rolls weather, getting lost and wilderness events, spends Rations and Fatigue on everyone's sheet, and an encounter can drop its creatures straight onto the map.
• Dungeons: the combat tracker runs exploration turn by turn. It shows what each character is doing, offers the rulebook's actions with their rules, tracks how far each token moved (with an undo), and says when the rules call for a Dungeon Event. If a fight breaks out, the dungeon picks up again on the same turn once it ends.
• Stores: ten small ones come ready, from the Weaponsmith to the Tavern. Stock your own by dragging items onto its shelves, open it on every player's screen, or let players walk in from their own sheet. Players fill a cart, and the store checks both their gold and their free slots before anything changes hands.
• Unknown gear: any item, from a relic to a strange potion, can hide behind the name, picture and appearance the Warden gives it, unusable until it is revealed.
• Factions that play: agents in rank order, an agenda to tick off, and buttons for faction actions and opposed saves.
• A party sheet that shows everyone's HP, attributes and load at a glance, plus the followers travelling with them.
• Live rules in your notes: write [[/save WIL]] in a journal and it becomes a clickable save. A trap written as [[/damage d6 STR]] rolls its damage against STR instead of HP. When a character dies, you can promote a hireling to a player character.

All the game content you need is already inside:

The ink-on-paper design uses Lora, the typeface the Cairn books are set in. A new world opens on a welcome scene with its own music, and every player finds the saves, the Die of Fate, Rest, Restore Abilities, the Rules Summary and the Calendar already on their hotbar. With Dice So Nice installed, you roll a custom 3D Cairn d20.

In Foundry's setup screen, go to Game Systems → Install System, search for Cairn 2e and click Install. Or paste this into Manifest URL:

https://github.com/brunocalado/cairn2e/releases/latest/download/system.json

Then create a world with the Cairn 2e system. If you want players to build their own characters, open Configure Settings → Permissions and allow Create Actor for players.

Recommended modules (optional):

• Dice So Nice rolls the 3D Cairn d20, and the other dice in a Cairn Blood Moon theme that each player can change.
• Light Sources lights torches, lanterns and candles from the token HUD and spends their uses. A lit torch is the torch itself: remove it from the sheet and it goes out, hand it to another character and it arrives lit, and a module that carries items onto the map, such as Canvas Loot, takes the flame with it.
• Automated Animations, with JB2A Patreon and PSFX, animates and sounds Cairn's weapons, monster attacks and spells. The system adds its entries to AA's menu once, and your edits to them are kept. A world setting turns this off.

The user guide covers everything in detail: the character creator, the sheet, rolling in play, every Warden tool, containers, and the API for macro and module authors.

The system is in English. A translation is a separate module: to make one, see Translating Cairn 2e.
