Later migrations by other groups such as the Akan, Ewe, and Ga-Adangbe into Guan-settled areas would then have led to the development of Guan-speaking enclaves along the Volta and within the coastal plains.
As far as the other Guan subgroups are concerned, the Anum-Boso speak a local Ewe dialect, whereas the Larteh and Kyerepong have customs similar to Akwapim groups.
Nana Offei Kwasi Agyeman of the Aduana fame, a trader from Gyakiti, and a chief in his own right, had already left Akwamu with his people to live at a village called Adenya.
When the Akwamus' brutalities on the Guans and the Kyerepongs had gone beyond control and intolerable, the leadership had these settlers summon a meeting to chart and discuss a way out of their predicaments.
Gyadu Nkansa, then the king of the Guans and in that capacity the leader of Akuapem, in his old age and at his hour of death just at the beginning of his successor Ohene Berentiri gave authority to Ofei Agyemang, chief of Gyakiti and Sediesa (Asare Diedsa), chief of the Kyerepongs to extend an invitation to the Akims for assistance to fight the Akwamus.
Unable to withstand the shock of this highland change, the Akwamu forces broke, scattered and fled across the Volta river to present-day Akwamufie.
The remnants of Akwamu, the people of present-day Aburi and its envious readily submit themselves to the new power, and thus pave the way for the establishment of Akuapem State as enshrined in the famous Abotakyi Accord in 1733.
The common enemy (the Akwamus) having been driven away, and besides the fear that they might return, came the need to institute an internal security system to face any future eventuality.
The Gyase position went to Nana Akompi Kwatia of Amanokrom for he being the brother of Okyenhene, and also custodian of Okuapehene palace regalia and paraphernalia.
