Okay well this takes place after Book 4 for Legend of Korea and in 1852 in Dishonored. That year, Emily sends an exploration fleet eastwards to discover the Avatar world, where numerous explorers before have claimed to have seen it and dubbed it the “New World”. Eventually, they reach the shores of Republic city, making first contact.



(The Empire of the Isles islands are much larger here in order to make them more equal to the Avatar world which inhabits one side of the world while the Empire inhabits the other side of the world.)



Eventually, both sides attempt to negotiate relations between the two worlds, despite the tense atmosphere due to their different cultures.



Meanwhile, in the Empire, a mysterious figure leads a coup against Emily and gains control of the Empire, putting it on a war path with the Avatar nations. Korra and her friends must now team up with Emily, Corvo, and their allies to help retake the Empire before the world is plunged into war.
