It all starts with the construction of the River Incursions Dock, where we recruit specific Jomsvikings for these navigations. Vagn, a dark-skinned Viking, is our guide in this expansion. We chose one of the six rivers on the map to navigate and we went on the attack! The new maps are all based on river systems, which consist of a meandering main course with islands and interconnecting side channels. Scattered along the banks of the river are civilian settlements, military compounds, monasteries and druid camps. Each of these location types offers different challenges and rewards. The maps are: River Exe, River Severn, River Dee, River Erriff, River Berbha and my favorite: the River Rhine (it's in France and it has a very big city, I was impressed!).
