Cairn 2e
Cairn 2e is a classless fantasy adventure RPG in the Into the Odd and Knave lineage. It uses simple saves, inventory-driven characters, and clear Warden procedures for dangerous exploration in strange woods, ruins, and wilderness routes.
OSR/NSR fantasy • Classless • d20 saves • Inventory-driven • 3-5 players + Warden • Low prep • One-shot and campaign friendly
Cairn 2e is Yochai Gal's refined edition of a classless, rules-light fantasy RPG built from Into the Odd and Knave influences. It keeps characters simple, makes inventory matter, and gives the Warden practical procedures for exploration, travel, danger, and discovery.
Theme and Setting
The default imagination is a mysterious Wood full of settlements, strange folk, buried places, and threats that do not scale to the party's comfort. Cairn does not ask the group to memorize a large canon; it gives enough texture and tools for the table to make a grounded, perilous world in play.
How Play Feels
Characters are fragile, capable, and defined by what they carry. Saves are quick, combat is dangerous, and good play often means gathering information, using tools, negotiating, avoiding fair fights, and treating time or light as real resources.
What Makes It Distinct
Cairn 2e's strength is practical clarity. It is lighter than many OSR games but more procedural than pure freeform fantasy. The Warden support makes it especially useful for groups that want old-school exploration without dense rules or long prep.
Where It May Not Fit
It may frustrate players who want class abilities, heroic durability, balanced encounters, or lots of build expression. Cairn is best when danger is meant to be negotiated with, fled from, or solved sideways.
What this game is about
A strong fit for groups that want fantasy adventure with a clear play identity, with exploration-Driven helping define the experience.
