Tretchen

''We set our scene in the Kingdom of Tretchen, where birds sing and a gentle breeze flows across the sunny summer hills. War hasn’t been seen in centuries after the four great Knights of the Round Table led their fellow warriors in defeating the evil forces of Hades, driving his fiends back through the portal to the Nine Hells and sealing it shut. Nowadays, soldiers are still trained to maintain order, but violence has been scarce on the Palm Island. It’s not a very busy day at the castle where we see our four heroes waiting outside the gates. The sound of swords clanging from soldiers training can be heard from inside the walls and the hustle and bustle of the market clatters in the background.'' -The Knights of the Round Table Campaign

Territories
It originally took up all of Palm Island until the Civil War caused it to split, then the emergence of Nerr shrinking it even further.

Religion
Pelorism is rather popular.

Foreign Relations
Phlegathos They established themselves as an empire after the beginning of the Knights' War, thinking they needed unity and a government to fend off the forces of Hades. Four leaders rose up, the Knights of the Round Table, and defeated Hades's devils and demons, casting them back into the portal from the Nine Hells they had entered from.

Vexon At one point, Tretchen went to a civil war, splitting into Tretchen and Vexon. After the war, the two nations still maintained friendly relations.

Nerr Once Nerr emerged from the Neran tribe, the Tretchans were very opposed to them, seeing them as a threat to their power as they controlled all of Palm Island. This only heightened when they declared themselves a nation. Tensions were high for years until Tretchen declared war on Nerr, starting the Neran-Tretchan War, which extended until the Highwaymen killed Emperor Schup, taking his crown. Shortly after, the Highwaymen attacked and destroyed Castle Claudio.
