Nirualkusaria

One of the tribes that ventured across the Equinswade was the Nirualkusaria, and they were only a small portion of the over all group that made the Journey. Their relevance is that they were the only tribe to begin developing an actual way of communication that could be recognized. Their efforts created a language that most of the other tribes began to speak, either by natural spread or through conquest, and would later transition into the Niruken language of the Northeastern Peoples.

Geographical Distribution

Originally the language was held within the settlements of the early tribes, and their control was largely over the eastern bay. Their settlements were small but plentiful, and many among these speakers began to raid the surrounding tribes and people around. They would take control of coastal settlements, but would occasionally chase fleeing warriors towards their inner continental settlements. These attacks would either be rousing successes with the attacking forces burning and razing all present, or was a complete defeat as the defenders would be properly prepared. 
Eventually the spread of the language began to happen through trade as not every member of the tribe wished to be a raiding warlord. As the society overall began to shift towards a split of fighting or creating, different professions and needs presented themselves. Trade was one of the first changes, with their naval control the merchants travel up and down the coasts and traded goods for new and unique materials.  As the spread of goods from these merchants reached further and further settlements, the adoption of the Niru language was beginning to solidify. Trading was easier and communication began to quicken, however variations of the language began to appear as the tribe began to grow. Merchants spoke a more formal version, while the raiding warriors seemed almost savage in comparison. The everyday person would adopt the tone and speech of the surrounding peoples, eventually leading to several accents.
