Adventum: Where Stories Live

Welcome to Adventum

 
Adventum is a home for the imagination
Mine, and maybe yours too. It’s a world-building engine, a myth-rich D20 system, and an open invitation to create. Whether you’re here to explore the lore, write your own legends, or escape into stories that matter, you’re in the right place.  

This is a place where

Lies can tell truths
Stories can bring hope
And anyone can belong

What We Believe

Creative Freedom

The tools belong to the builders, not the gatekeepers  

Integrity of Lore

Worlds should be deep, consistent, and worthy of belief  

Accessibility

Core content is free and open to use  

Inspiration over Imitation

Spark new myths, don’t just retell old ones  

Empathy for the Outcast

For every kid who didn’t fit in… until they found stories
 
A Note From the World Building Team   This world is still being forged — just like the legends within it. I'm building a new kind of open mythos: a home for storytellers, game masters, and worldbuilders.   The lore is evolving. The rules are forming. The spark is here.   In the meantime, feel free to explore what exists — from planar overviews to the index of what's to come.  
Where the myths feel real.

Licensing & Usage
Adventum is a gift to worldbuilders.   You’re free to use the core lore, planes, mythic structures, and D20 system mechanics I create here in your own campaigns, homebrew worlds, or projects. This world is being built to inspire creativity — not gatekeep it. The world itself is open. The stories within it are mine.   That means Everything labeled as mechanics, planar structure, or core lore is intended to be public domain or openly licensed. All named characters, narrative arcs, and published novels remain protected under my intellectual property. You can build your own myth using Adventum — just don’t claim or sell the original characters or stories I’m telling within it.   This is a forge. You are welcome here.
