Your World. Your Creation.

So you built a world! Maybe every window is stained glass. Maybe everyone is expected to join one of six extremely quirky guilds. Maybe it's full of rapidly multiplying critters that everyone loves... and that surely won't cause trouble of any kind. Right?

Now do something with it.

Your World Is Yours

Sell it, share it, stream it, eat it, or keep it for the lucky few at your table. If you made it, it's yours. Duh.

However...

You may freely reference Arium's rules, but you may not reproduce text or artwork from Adept Icarus's Arium products.

Put the Logo on It

You may use the Grown With Arium logo on original projects built from worlds you created with Arium: Create or another Arium worldbuilding tool.

If you use the logo, include this attribution:

Build a World, the Arium Way

Everyone has ideas. Fun ones, strange ones, occasionally wacky ones. Not all the time, but that's ok because ideas are cheap! Toss whatever you have on the table. Talk about it, combine it, and vote for your faves. Somehow, you've made a world that feels real and none of you could have made it alone.

The Storm

Each of Arium's seven Steps uses a Storm: Ideating, Collaborating, and usually Voting. Lacunae skips the vote—if someone says it doesn't belong, it stays out.

The group decides how many votes it takes to make ideas part of your world's canon.

The Steps

Players will perform a Storm for each of the following Arium Steps:

Grab those sticky notes that nobody can stop talking about. Start there, and as folks sometimes tell their dogs: "Make!"

Look What Grew

Ideas that refuse to stay on sticky notes can become something more. A setting, some fiction, a complete game? Tell us about yours, and maybe we'll feature it!

"What did the creation of our universe sound like? We now know, unequivocally, the sound of creation was a roaring, babbling, mish-mash of voices trying to talk over each other in a crowded convention center ballroom."
