The Three Great Wars of Legendaria: Conflicts That Shaped the World We Know

3 min read

When Rory pried up the loose floorboard in her grandmother’s cottage and found an old sword wrapped in oilcloth, she expected rust and cobwebs. What she found instead were three sets of engravings — names, dates, and battle crests she did not recognize. Six months of relentless research later, she had pieced together something extraordinary: a timeline of the Great Wars of Legendaria history, the three cataclysmic conflicts that cracked the world open and stitched it back together in an entirely new shape. What Rory uncovered, scholars have debated for centuries. But the sword did not lie. The wars were real, and their echoes are everywhere.

Why the Great Wars of Legendaria History Still Matter Today

Legendaria was not always the layered, complicated world that young adventurers like Ollie and Jake wander through today, arguing about which mountain pass leads to the Obsidian Marshes and which one leads to certain doom. Before the Three Great Wars, Legendaria was younger, wilder, and dangerously unbalanced — a place where magical power pooled in the hands of a very few, where ancient creatures roamed without boundary, and where the borders between the mortal realm and the mythic deep were practically nonexistent. The wars did not simply redraw maps. They rewrote the fundamental rules of how the world works.

Understanding these conflicts is not merely an exercise in dusty history. Every enchanted artifact, every cursed forest, every alliance between human kingdoms and creature-clans that exists in Legendaria today was forged — or shattered — during one of these three pivotal periods. If you have ever wondered why the Thornwood Elves refuse to speak after sunset, or why the Saltmere Giants kneel before no throne, or why Dame DrizzlePox keeps a sealed iron chest that no one in her household is permitted to touch, the answers live somewhere in these wars.

The RPG Sourcebook That Lets You Run These Wars Yourself

If Rory’s discovery of those battle crests and timelines has left you hungry to *experience* the Three Great Wars rather than just read about them, this is the sourcebook that transforms Legendaria’s history into playable campaigns. Building your own world-shaping conflicts requires the right tools—and this d20 system guide gives you everything you need.

What works

  • Comprehensive campaign architecture for designing multi-phase conflicts with lasting political and geographical consequences, mirroring how the Great Wars actually reshaped Legendaria
  • Detailed worldbuilding frameworks that help you establish factions, battle crests, historical timelines, and the kinds of discoveries (like Rory’s sword) that anchor players in lore-rich settings
  • Practical stat blocks, encounter scaling, and NPC creation tools so you can bring the named combatants and major battles to the tabletop

What doesn’t

  • If you’ve never run a d20 tabletop RPG before, this sourcebook assumes you’re already comfortable with the system’s mechanics and character creation
  • You’ll still need to adapt the framework to Legendaria’s specific magic systems, pantheons, and factions—it’s a toolkit, not a pre-built campaign setting

This is perfect if you’re ready to move beyond reading about conflict and actually *orchestrate* it—but not ideal if you’re new to running games or looking for a Legendaria-specific campaign already written for you. The Ultimate d20 RPG Systems: Create Your Own Tabletop Adventures
