Marleybone is the third world out of. . . how many main worlds are there. ..

Wizard City Krokotopia Marleybone MooShu Dragonspyre Celestia Zafaria Avalon Azteca Khrysalis (where I am currently) Polaris Mirage Empyrea

And then Grizzleheim/Wintertusk, Aquila (technically an extension of Wizard City, but I'm counting it as a world), and Wysteria are side worlds.
