Each of the six "miigis" established separate "doodem" (clans) for the people. Of these "doodem", five clan systems appeared:  After founding the "doodem", the six "miigis" returned to the depths of the ocean as well. Some oral histories surmise that if the seventh "miigis" had stayed, it would have established the "Animikii" Thunderbird "doodem". The powerful "miigis" returned in a vision relating a prophecy to the people. It said that the Anishinaabeg needed to move west to keep their traditional ways alive, because of the many new settlements and people not of Anishinaabe blood who would soon arrive. The migration path of the Anishinaabe peoples would become a series of smaller Turtle Islands, confirmed by the "miigis" shells (i.e., cowry shells). After receiving assurance from their "Allied Brothers" (i.e., "Mi'kmaq") and "Father" (i.e., "Abnaki") of their safety in crossing other tribal territory, the Anishinaabeg moved inland. They advanced along the St. Lawrence River to the Ottawa River and through to Lake Nipissing, and then to the Great Lakes. The first of these smaller Turtle Islands was "Mooniyaa", where Mooniyaang now stands. Here the Anishinaabeg divided into two groups: one that travelled up and settled along the Ottawa River, and the core group who proceeded to the "second stopping place" near Niagara Falls. By the time the Anishinaabeg established their "third stopping place" near the present city of Detroit, the "Anishinaabeg" had divided into six distinct nations: "Algonquin", "Nipissing", "Missisauga", "Ojibwa", "Odawa" and "Potawatomi". While the Odawa established their long-held cultural centre on Manitoulin Island, the Ojibwe established their centre in the Sault Ste. Marie region of Ontario, Canada. With expansion of trade with the French and later the British, fostered by availability of European small arms, members of the Council of Three Fires expanded southward to the Ohio River, southwestward along the Illinois River, and westward along Lake Superior, Lake of the Woods and the northern Great Plains. In their western expansion, the Ojibwa again divided, forming the "Saulteaux", the seventh major branch of the Anishinaabeg.
