AppearanceEpic's Subspace looks like a floating island with a hole in it to allow a flashing light bypass out and above.
If you do not have an Epic, then you can still visit the area and explore, except you cannot participate in the games. For example, if you have a Magmischief, then you can play the quest when you tap on Magmischief and so on with the other Epics.
There are all 5 classes in Epics Subspace, though some pets cannot be caught.
