Somewhere in the north of the local sea region, an archipelago resided amongst the tides and the blue skies above with a lone island at its center. It was wide and vast, rivaling a particular continent of the former world, Australia.
The island was the gateway of humanity into the Ferus Sea and the New World. It was the place where it all began, the very island that brought about the Age of Exploration.
The Colonial Dominion of Terra.
Terra was a very distinct island with rich diversity and natural resources. It was the first island colonized by humanity, making it incredibly established in the New World.
It brimmed with port towns and trading ships facilitating inter-seas trade, shrouding the island with never-ending commerce. Because of this trade, the Colonial Dominion of Terra was amongst the richest colonies in the Ferus Sea.
It was a place of opportunity for humanity's explorers and dreamers.
In simpler terms, it's frontier.
