THE DOOM CODEX

60 Campaign-Defining Crises, Disasters & Threats for 5E-Compatible Fantasy

Your campaign doesn’t need another villain.

It needs a problem that won’t wait.

The Doom Codex gives Game Masters 60 ready-to-run crises that can be dropped into almost any fantasy campaign. Wars erupt, rulers fall, harvests fail, plagues spread, trade routes collapse, monsters migrate, and cities begin to break under pressure.

Each Doom is more than an adventure hook. It is a living campaign engine with escalating consequences, factions, NPCs, encounters, hard choices, and multiple possible outcomes shaped by player decisions.

Run a Doom as a short story arc, a major chapter of your campaign, or the foundation of an entire adventure.

60 DOOMS ACROSS 6 CATEGORIES

WAR, CROWNS & REBELLION

Civil wars, invasions, succession crises, rebellions, unpaid armies, and collapsing authority.

Examples:
The King Is Dying
The Heir Has Disappeared
The Capital Is Surrounded
The Army Didn’t Come Home

FAMINE, TRADE & RESOURCES

Failed harvests, shortages, disrupted trade, collapsing industries, and fights over limited resources.

Examples:

PLAGUE, MIGRATION & SOCIETY

Disease, quarantine, refugees, overcrowding, unrest, and communities pushed beyond their limits.

Examples:

LAND, WEATHER & DISASTER

Floods, droughts, fires, storms, earthquakes, harsh winters, and environmental collapse.

MONSTERS, BEASTS & THE WILD

Creatures treated as regional threats rather than isolated combat encounters.

Collapsed bridges, blocked ports, broken roads, failing aqueducts, damaged walls, and other systems civilization depends on.
