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.
