Blood, (noun); in Kuriian military organizations; a leader of a military unit of varying sizes and strengths depending on his rank; the smallest Unit led by a Blood is 'Kur' or 'Beast' followed by 'Band' 'March' and 'People' each unit a large multiple of the former.
The military Kur, in this sense a unit, is commanded by a "Blood." This seems peculiar perhaps but is explained by ancient Kurii belief, that thought is a function of the blood. One "thinks" thus with one's entire body, not just the brain. Contemporary Kurii understand, naturally, that cognitive processes brain-centered, or largely brain-centered, but the ancient terminology, in their songs, poetry, and even military lexicon, remains. Analogously, humans continue to speak of affairs of the heart, a man of good heart, that someone has a big heart, etc., which terminology perhaps lingers from the when the heart was regarded not as a chemo-mechanical pump but as the throne and home of the emotions. The commander of a military Kur, thus, might better be thought of as the "brain" or "mind," but continues, in their languages, to be spoken of as the "blood." A "blood" thus commands the two eyes and the two hands. Twelve "Kurs," the sense of military units, constitutes one "Band." This one hundred and eight animals, including subalterns leaders, and is itself commanded by a "Blood," whose rank is indicated by two rings on the left arm. Twelve of these Bands constitutes a March. A March thus consists of 2,160 animals, or, counting the commanders of each Band, 2,172 animals. A March is commanded by a Blood, whose rank is indicated by one ring on the left arm. The rings of rank are quite plain, being of some reddish alloy, and are distinguished from decorative rings, of which many Kurii are fond. Kurii, generally, like men, seem vain beasts, there appears to be an inverse correlation between height of rank and intricacy and variety of ornamentation. The higher the rank the simpler is likely to be the ornamentation. The commander, or Blood, of a March wears only a single, simple reddish ring. Whether or not this simplicity is honored off duty, so to speak, or in their privacy, I do not know. I further do not know the full significance of the rings. I do not understand how they are earned, or what is involved in moving from the "second ring" to the "first ring." I do know that rings are welded on the wrists of the beasts. The iron files of the Goreans, incidentally, will not cut the alloy.
