The Oasis is a location in the world of Fantage. There are two ways to get here, one is the Dock, and the other is by map.
It is basically a floating island above Fantage. You can also find Captian Cody here, but not recently.
Here, you can play a new card game, called Card Quest. You can also buy cards to use in this game. There used to be Raj's Rare Finds, but that shop has been removed.
