“ In a warrior based society, when you make a threat of violence or death towards another, you had better be prepared to back it up with your weapons.

Trying to back out at this point is considered cowardice and results in being disgraced.”
“ Certain trees have sap that is filled with magical potential. Their sap is harvested and distilled down to produce various types of potions, much like maple syrup is collected in some areas. The magical effects of these syrupy potions are often fairly trivial; perhaps they simply cause the imbiber to grow hair more quickly, summon butterflies, or walk a few inches above the floor. People enjoy the syrup as a flavoring, instead of imbibing it for its magical powers.”
