A Resonite world is like a level or a map. A world is made up of a single Slot -- the Root slot -- and metadata, like the name and owner of the world.
Users can create new worlds from the Dash Menu. When saved, a world appears in the inventory as a World Orb. This can be spawned and interacted with to create a new Session running the world.
However, this World Orb is just a link to the world; the world itself is stored in the "My Worlds" category of the world's creator.
Worlds can be published using the World Publisher. To learn more, see Submitting Worlds
