Military action
As the Calcians struck further into the continent, they found themselves faced with human tribes in the woods and plains, but even deeper, were creatures they hadn't seen for years.
The found Kobolds, elves, and human tribes deep in the unclaimed land of Okigira. While many were easy to reason with, some made it their mission to keep these new shiny people out of their lands. This was largely unsuccessful, due to Calcia's larger amount of warriors, as well as their discipline and training. Many tribes only managed to keep them from their individual lands, and even then they soon filtered out into Calcian people.
