Maybe there should be two Zulu states. The Kenya Zulu would always appear in Ethiopia and the Kongo Zulu would always appear in Mali.
Then add Atlantean, Inuit, Icemen, and Sea Peoples invasions
.
Atlanteans would be Africans or Mongols with Byzantine clothing, Inuit would have Mesoamerican faces but European cloaks and other head covering cultural clothing, Icemen would be Russians that always have white hair, and Sea Peoples would be Mongols with African attire who appear in the Mediterranean.
Nowhere is safe from the onslaught.
