Technology
Technology in Kitezh is limited to the Viking era (bronze and iron), with a few innovations from Amber and other shadows used mainly in the Heart.
Trade
Natural resources of the kingdom include gold, lumber, ice, animal products, and wheat. Kitezh exports lumber, gold, dried meats, hair-on reindeer and pony hides, cured leather goods, especially from the North. Ship building and fine craftsmanship are the businesses of the Heart; ship repair and lumber trade are the domain of the Lowlands. Whaling is a thriving industry in all of Kitezh, and whale products are put to many uses.
Time flow is the same as Amber.
Weaponry
According to custom, all free Kitezhka men are required to own weapons. These arms are indicative of man's social status: Only the wealthiest warriors would have a complete ensemble of a helmet, shield, chainmail shirt, and animal-skin coat, among various other armaments; his arms would be long and short swords and an axe and spear. Men of lesser means would have leather armor, if any, and fewer weapons. The poorest might only be able to afford a single weapon (often an axe, since it is useful for farming and ship building, or spear) and perhaps a shield.
