Can we relocate in this game? If yes, how?

Two ways, go to the map screen and move around until you get to a vacant lot. Click it and click Relocate castle. If you have not obtained one you will either need to purhcase one with sapphires or through available packagages available for purchase. the second way, go to your items, then the combat tab and scroll down to the Gateways section. Any you have will be located here. You can use the gateway of chance as well to move you randomly somewhere on the map away from your current location.
