All routes leaving provinces are hidden, so need to be discovered through exploration. This makes the exploration of Hades a very slow process. There are both hidden and visible graveyards scattered around, and these usually lead to a province in the main world far removed from the graveyard you used to enter Hades. Occasionally there will be more than one graveyard in a Hades province, but this has been observed only very rarely. It is important to note that the graveyards are in the main world, and although movement from Hades to the graveyard is free, movement back into Hades requires another payment to the Gatekeeper Spirit of Hades.
