Chief's Hall

The Chief Hall is the symbol and foundation of the clan. It is the Vikings' most sacred building that represents their bravery. In some ways, the Chief Hall is more important than Valhalla, as it represents the dignity of the living. Upgrading the Chief Hall increases the clan's potential and determines the development scale of the City. A grand Chief Hall means the clan can go further.
