The Erithians hail from Erytheia, a place where people know about magic, mythical beings and supernatural forces. But the Mayra tribe lives in close proximity to both Erytheia and Erithia. For a long time, bands of nomads and monsters fought against the Erythians in vicious battles. No one knows where the monsters came from or when they appeared at the Borderland. The Urue invaders attacked many faraway countries before attacking Erithan. Invaders caused strife in the Erytheia territories for a long time. But their raids eventually became more problematic, as the inhabitants of these areas teamed up with tribes of Sarii living outside the Tranquil Plains to eliminate them from existence. This was due to Invaders’ worldwide threat that had caused neighboring lands to suffer dearly. Urus were routed out of their Erytheia territory and heading to the Tranquil Plains through their land as a whole. Both the opposing combatant armies and their monstrous battles increased in ferocity and audacity. There was no comprehensive plan in place to counter this resistance. Once developing the idea of fortresses to defend territory against large-scale enemy raids, the army were able to clear the surrounding area over time while they slowly defeated their enemies near the Frontier.
