How do i return to ARRAGOT once i've completed Campaign.

How do i get to "ARRAGOT" once i've completed campaign. Going through the portal sends me to the riverbank and I cannot select it on the waypoint map.

Every time you go trough the time portal you switch between past / present, so if you are in the wrong time you need to go trough the time portal again. (It switches between past/present on the world map when you go to the riverbanks trough the time portal)

Then you can either run trough the first zone of act1 cruel, or make a portal to town and type /hideout. Then select Arragot from a waypoint.
