Can an Open Fantasy Universe actually work?

Hi everyone!

For the past few months I've been working on a personal project called Aperion, but recently I realized that what I'm trying to build isn't really "just another fantasy world."

It's more like an experiment.

The idea is simple.

Instead of creating one massive setting that only I control, I want to create a universe with a shared set of fundamental laws.

Things like:

• How magic works.

• What souls actually are.

• Why life and death exist.

• The basic rules that govern reality.

Everything else is open.

Imagine one world where necromancy became the dominant form of magic and civilization slowly collapsed.

Another where magic accelerated technological progress.

Another where humanity almost abandoned magic entirely.

Every world would be completely different, but all of them would follow the same universal laws.

The long-term goal isn't just writing lore.

I'd like to build a platform where writers, artists, RPG creators and game developers could contribute their own worlds, kingdoms, cultures, creatures or stories.

Not as fan fiction.

Not as alternate timelines.

But as independent worlds that belong to the same universe.

Of course, this raises a lot of difficult questions.

How do you keep quality high?

How do you prevent contradictions?

How do you allow creativity without turning everything into chaos?

That's exactly why I'm posting here.

I'd love to hear honest opinions from people who enjoy worldbuilding.

Does this idea sound interesting?

What do you think would be the biggest challenge?

Would you ever contribute to a project like this?
