Population Migration / Travel
More gates were opened to allow all 12 islands to be populated.
Over the next 300 years, more gates were opened to Vinland bringing more humans over. Each set of gates brought humans from the same tribes to each of the Islands. Hendursaga God of Law and Mammetun Goddess of Chaos were looking for the warlike humans that were known to them from before the separation. Unfortunately what they found was a people that was still strong in their belief of the 10 despite being cut off from them and believed in working together to live.
This lead to the Humans being able to create settlements and clans but did not give them the drive to take over the islands from the lawless groups that also inhabited them as the 10 had 1st planned.
around 650AD to 700AD the 1st "Vikings" arrive in Vinland and give it a name. Before this time it was just known to the natives as Gaia. They bought the level of violence that was being looked for by the owners of the Pinnacle of Mammetun. While still being able to traid and work with those they conquered.
Gates were open in selected areas of their homelands and in the areas off Vinland they had taken over. Allowing entire Norseman villages and war party's it travel to the Islands of the Clans.
They quickly took over the existing human clans, then started to increase their clan power by conquering the other groups on their island.
