The World of Destiny

The World of Destiny is a world only accessible through the Transport-o-Matic. It is fairly prominent in Season 3.

In the novel
In chapter 11 of the mega-novel of AV lore, "Adrellia Village #1 - Kingdom of Darkness," Drake believes that his dreams are telling him to go to the World of Destiny. It is described as "a nice place where people will eventually meet their destiny." The novel also alludes to a place called the Crossroads of Magic. This hasn't been explored in the series as of December 2017. "There was an exit to the World of Destiny—but then you’d have to pass by the Crossroads of Magic—evil shadow creatures roam around that place."

In the episodes
The World of Destiny is first introduced in King William's Pursuit of Happyness. The environment is best described as strongly resembling Traverse Town from Kingdom Hearts. The main function of the World of Destiny in the beginning of Season 3 is that it provides a platform for Drake to fight in the Coliseum and make money.
