The Isle of Ruk and Dungeon of Klinis

The Isle of Ruk and the Dungeon of Klinis

A sandbox adventure module and mini‑setting for classic fantasy play.

Explore the bustling port town filled with factions and intrigue, wander the wilds where strange creatures stalk, and delve into the dungeons. New monsters, magic items, and two new character classes bring fresh flavour without adding rules.

At the island’s heart stands the Dungeon of Klinis a three‑level ruin carved deep into the mountain, filled with traps, factions, and long‑buried treasures waiting to be uncovered. Whether your table prefers exploration, intrigue, or old‑school dungeon delving, Ruk offers a flexible foundation for emergent play.

Inside you’ll find:

A lively port town packed with NPCs, factions, rumours, and adventure hooks
A hex‑crawl wilderness full of oddities, encounters, and strange phenomena
The Dungeon of Klinis, a multi‑level adventure site designed for classic play
New monsters and magic items that add flavour without adding rules
Two new character classes to drop straight into your campaign
A setting built to be hacked, expanded, or used as a launchpad for your own stories
Design Inspirations

This project draws on the spirit of Gary Gygax’s classic article “How to Set up Your Dungeons & Dragons Campaign – and Be Stuck Refereeing It Seven Days per Week until the Wee Hours of the Morning!” and the practical creativity of Ray Otus’s workbook approach to worldbuilding.

The map were drawn with inspiration from Niklas Wistedt (Paths Peculiar) how to draw basic dungeon maps.

The Graves design aided by James Holloway's The Tome of Tombs.

The earliest seeds of the Isle of Ruk emerged while designing a character class for the OSE Class Jam, eventually growing into a full mini‑setting and adventure module,
