I was wondering how the travel route from the north and to the summer campaign is. Are we going through the terra portal in Erengard or do we have to travel to the west and use their Adria portal, for as far as I know the portal in the north doesn't have a dial

Hey,
after they have finished the repairing of the terra portals, the whole army would use the gate in Erengard.
But at last we have to use the final aeris portal aka Greifenportal to get on the fuckin island...
