Kingdom of Kraten.
It bordered Aurgoth to the West and Darkshore to the east. It largely depended on the sea trade as it was connected to the ocean to the South. It's population was the highest amongst all the tier 1 nations and so was its land area. The capital- Rumenshire- was one of the major cities of the Confederation, known for its vibrant markets and trades.
Even though it was just a tier 1 nation, it was quite influential in the Confederation. After all, it was one of the three major tier 1 nations, a country capable of holding off against a tier 2 nation for some time on its own. Moreover it shared friendly relations with both of its bordering kingdoms.
The reason it was able to be a top dog amongst the tier 1 kingdoms and become a leader of the T1 alliance was simple- it had a couple of level 9 circlers and a handful of tier 8 circlers.
But unbeknownst to the common citizens and lower nobles of the nation, the kingdom was in jeopardy.
