There were four brothers named Malu, Sigai, Kulka and Seou. Each were blessed with special powers. Each travelled in canoes to colonise a different island. In this way, their influence would spread over a far greater domain. The people followed their laws and were united in a common bond of brotherhood. When Sigai was asked where he intended to go, he pointed his nose to Yam Island (Iama). Diving into the sea, he changed into the form of a Kurrs (hammerhead shark). Arriving at Zagwan Point on Yam Island, he was worshipped as the god of war and created a religion with strict disciplines based on warfare.
