Rapwi was in the books we had read. He is the teacher of the famous Mao Pialug 'The Last Navigator.' These men are revered across the Pacific (anyone who knows ancient navigation knows these two). It is a dying skill consisting of navigating by the stars, the wind, the birds, the current, and the temperature among other things. The art of canoe building is equally revered. These men are truly god-like in stature amongst seafarers across the Pacific.
