Upon passing through the beach tunnel for the first time you will be offered the quest Eine Vision der Furcht. This is an introductory quest for the zone and will guide you to many of the major landmarks in the western half of Feerrott.
Feerrott Quest line Information
There are separate versions of each quest in this timeline for good and evil people, but they are equivalent - good and evil people can work together on them. Regardless of your alignment, there are four solo quest lines for you.
One of the quest lines gives permanent access to the solo instance Cleansing of the Cove (Zone) when completed. This is a great solo/duo instance for levels 35-40.
