If Edolas should be in the story, I think there should be more of a reason for them to contact each other than just that both are under attack by the Fire Realm.

Maybe the Fire Realm first attacks Earthland. There they find out that E.N.D. hid the weapon in Edolas and go there next, of course with our heroes hot on their heels.

This way the contact between the worlds could be established in a way that seems more natural to me than the Fire Realm just rushing into a two-front war when they only really need to attack in once place to fulfill their objective.

Or maybe the weapon was split in two (or more) parts and at least one was sent to Edolas.
