Noble Kanohi are less-powerful masks that are most often worn by Turaga elders, although they can also be used by a variety of other species with only a minimum of training.  Although the abilities they grant to their wearers are not as potent as their Great counterparts, these masks tend to be easier to come by in comparison.  Masks may also be fashioned in these shapes out of respect for a leader, or simply to lend their bearers an air of wisdom.
