Seven Kingdoms is a real time-strategy computer game developed by Trevor Chan of Enlight Software.
In the game, you compete against up to six other kingdoms. You can
conquer your opponents by defeating them in war (with troops or
machines), capturing their buildings with spies, or offering your
opponents money for their kingdom.
The seven cultures you can choose to command are the Japanese, Chinese, Mayans, Persians, Vikings, Greeks, and Normans.
Each culture has its own weapons and fighting styles. Each culture can
also summon its own "greater being", each having different powers.
Fryhtans are fictional beasts that hoard treasure and hold "scrolls
of power", objects that enable you to summon greater beings. They are
quite powerful, and have been known to offensively attack kingdoms.
