The Wondrous Wandering Worldsmith has seen it all. They travelled far and wide, to the deepest reaches of the known universe, and didn't even stop. To be awarded this badge and stand as a veteran wanderer, you will need to submit each one of your articles in different worlds. That means that if you're also going for diamond, you will write articles in 32 worlds (40 if you're a super completionist).
