I think KI will take every world and insert peices of each world into 1 giant world with a boss at the end of every section like say a peice of mooshu like a corrupted Hmaetsu Village last boss is one of her minions there and it would go like this in the world. Ambrose is the one you talk to for every quest. you start out in a dark version of a peice of wizard city then once the boss there is done you move to dark krokotopia then dark marlybone and so on. But the bosses in the peices of the spiral in the final world are the last bosses of that world but WAY STRONGER
