What is this system

The third and most ambitious game built on the Into the Odd engine. You are wandering knights traveling through mythic lands. Each knight carries their own Myth — a personal destiny woven into the fabric of the world. The world is procedurally generated right at the table: oracles, tables, and hexes create a unique map for each group.

Setting

Dark Arthurian fantasy without elves or fireballs. Misty bogs, stone circles, forgotten kingdoms. The world is a blend of The Green Knight, Breton legends, and Norse sagas. Monsters here are mythic creatures, not bags of hit points.

What it looks like at the table
A new hex. You roll on the oracle table — 'A stone circle. Inside — a faceless knight, bound to an oak.' Your Myth says: 'Find the one who knows the river's name.' Is this him? You ask the knight. He answers in your father's voice. The season changes — winter arrives, and the world around you responds.

Key mechanics

Knight Myths

Each knight starts with a Myth — a personal destiny. It's not a quest from an NPC, but part of the character themselves.

Procedural world

Oracles and tables create the world right at the table. Each hex is a surprise for the GM and players alike.

Seasonal structure

The campaign is divided into seasons. Between adventures, the world changes — peasants build, enemies grow stronger.

Into the Odd core

Auto-hit attacks, saves, minimal rules — wrapped in dark Arthurian myth.

What people say
Mythic Bastionland feels like what D&D would be if it was designed today by someone who actually read Le Morte d'Arthur instead of Lord of the Rings.— u/knight_errant, r/osr
The procedural generation is incredible. I ran a 6-session campaign and never prepped more than 20 minutes. The oracles did the heavy lifting and the results were better than anything I could've planned.— u/hexcrawl_fan, r/rpg
