User summary: Riddaren (The knight) describes the world of the knight (games, hunting, tournaments and festivities), new weapons and armor and chapters on owning land (how to govern it and how to build fortifications). It somewhat supercedes "Krigarens väg" and is considered to be the first installment in the trilogy of books dedicated to combat and fighting in the world of Mundana/Eon. The other two books are "Vapenmästaren" (The weapons master) and "Krigsherren" (The warlord).
