War, like math, is a universal language shared by every strata of civilization. Warriors from all cultures have, in one form or another, prepared themselves physically and mentally for the task at hand. More often than not, stepping onto the battlefield meant risking bodily death.
With the end of natural life so near, many warriors would confer with the divine, looking for their blessing to carry them to victory. Some conjured animal spirits to lend them their strength while others requested that deities guide their blades.
These are the rituals that prepared the champions of various cultures to meet their fate.
