Have a rest at Viking Longhouse in Viking Village and pick up Fortbyte # 98 while you are busy!
The Viking Longhouse is located in Viking Village, on the mountain top east of Snobby Shores.
The Longhouse is located in the upper corner of Viking Village. Fairly easy to detect because it is the tallest building.
In the long house you will find the Fortbyte along the tables. It is also close to the campsite.
