A 242-PAGE NORSE-INSPIRED ADVENTURE FOR 5TH EDITION
Sail the Serpent Sea, raid forgotten shores, challenge ruthless rivals, and carve your name into legend.
Reavers of Oath and Ruin is a complete adventure for characters from 1st to 6th level, set in a brutal world inspired by Norse mythology. The book is packed with full-color maps, illustrations, monsters, character options, and everything needed to begin a saga of blood, glory, and ruin.

FROM THE LEAD DESIGNER OF BALDUR’S GATE, DRAGON AGE: ORIGINS, AND STAR WARS: KNIGHTS OF THE OLD REPUBLIC
Created by veteran RPG designer James Ohlen and the team at Arcanum Worlds, Reavers of Oath and Ruin combines dangerous exploration, fierce rivalries, desperate choices, and brutal battles across a mythic northern world.
FEAR NOT DEATH, FOR THE HOUR OF YOUR DOOM IS SET, AND NONE MAY ESCAPE IT
Grimnir is a land of cold seas and hard people, where survival must be earned and glory must be taken.
The gods remain silent within their Stone Court. Monstrous yoten gather beyond the horizon. Ancient grudges threaten to drown the clans in blood.
You are reavers, bound together by shared ambition. Aboard your longship, you will cross the Serpent Sea in search of gold, renown, and a place in the Halls of the Slain.
Every raid will shape your legend.
Every rival will remember your name.
Every oath will demand its price.
Better to fight and fall than live without hope.
For many live longer than they are worthy

CARVE YOUR LEGEND ACROSS THE SERPENT SEA
The heroes are not the only reavers seeking wealth and glory. Six ruthless raider captains sail the same waters, each commanding a dangerous crew and pursuing ambitions of their own.
They may become allies, enemies, rivals, or something far worse.
Your choices determine which settlements survive, which captains rise to power, and what songs will be sung of your deeds when the saga ends.
Will you earn a place among the honored dead?
Will you become rulers of the Serpent Sea?
Or will your names be forgotten beneath the waves?
