Abong Noga, a supposed king was revered as pioneer among the A·chik society. The A·chik followed nomadic pattern of living before coming to the Nokrek peak of Tura Range. It was the king Abong Noga who brought the A·chik to that region and initiated sedentary settlement pattern. With the passage of time, the population grew in size and space they occupy expanded, which later on came to be known as Garo hills. The legend of Abong Noga was not established on imaginary concept but based on real life events and characters. This is testified by the physical remains of Kosi in Nokrek Peak, the said abode of Abong Noga. Kosi is an ancient tradition of raising stone monuments on certain important social events among the A·chik.
