She nods and clears her throat. "It is not an oath until you clasp each other's hand around a double-edged blade, letting your blood mix. As you do this, the words are so: Blood for blood, bone for bone, life for life, until only we stride the earth. My life is in your hands, my blood is in your veins. Hold me well and I will lend you my strength; break your bond and may we both perish. Friendship I swear to you; an oath of clasped hands and shared heart."
