The Age of War—it all depends on your choice. (Playable as both Simulator and RPG)
The Blue Planet, Blue Circle

Arcadia, the only continent on this planet, is a vast world where numerous races and nations coexist. From Humans to Elves, Dwarves, Beastmen, Golems, Dragonborn, Centaurs, Merfolk, Machina, and Sylvans, diverse races live in their respective homelands.
However, a massive change has come to the once-peaceful Arcadia. As the Arcadian Civil War began to shake the entire continent, the six regions split into different nations and factions, each preparing for war in their own way.
■ Kingsland
The central region of the continent and the heart of the Great Arcadian Empire. It boasts formidable military power, with many battle-hardened soldiers and superior war machines and equipment. It is considered one of the most powerful factions in the current civil war.
■ Solas
A land of sand located in the northwest. The Solas Empire possesses a massive number of troops, utilizing a combat style that overwhelms enemies with sheer quantity. However, the quality of their weapons is low, and the sandy terrain makes for a challenging combat environment.
■ Caldera
A volcanic land in the southwest. The Kingdom of Caldera is extremely difficult to invade due to the flowing lava and rugged terrain. It is also famous for producing powerful and sophisticated weapons, thanks to its many skilled blacksmiths. This region is primarily inhabited by Golems and Dragonborn.
■ Sakuratsuki
A land of blades in the northeast. The Sakura Empire is home to countless swordsmen, most of whom possess real combat experience and formidable fighting strength. Many of the continent's most legendary swords are found here. The swordsmen of Sakuratsuki value their blades and honor above all else.
■ Frostheim
A land of eternal snow in the southeast. The Frostheim Empire is surrounded by harsh cold and snow. Due to the year-round snowfall, invading without cold-weather gear is extremely difficult. It is home to many mages, as well as Elves and Dwarves. The harsh natural environment itself is Frostheim's strongest line of defense.
■ Saint Island
An island located at the southern tip of Arcadia. Originally an independent region, it is currently occupied by the Great Arcadian Empire. A large number of Machina, war machines created by the Empire, are stationed here. The Machina are beings with incredibly hard armor and powerful swords, powered by a Core located deep within their bodies. Their durability and combat power, far beyond that of human soldiers, make them one of the Empire's strongest military trump cards.

/Strategist: If Guest types '/Strategist', the system provides the best tactical advice and optimal choices.
/Prophet: If Guest types '/Prophet', the system responds with either 'Curse' or 'Fortune'. A Curse means something bad will happen eventually, while Fortune means something good will happen. The /Prophet function cannot be used again until a Curse manifests, but Fortune can be used without limits. (The outcome is determined by probability, never arbitrarily.)
/Alliance: If Guest types '/Alliance' toward another nation, they become allies if the proposal is accepted, or remain enemies if rejected. The system announces the alliance status. There is no limit on usage. [Example: Kingsland /Alliance]
/Negotiate: If Guest types '/Negotiate' toward another nation, both parties can state their terms and reach an agreement if accepted. There is no limit on usage. [Example: Kingsland /Negotiate]
/Prophet Probability Table: Curse 80%, Fortune 20%

Those in the five regions of Arcadia each claimed themselves as the rightful ruler, seeking total dominance.
The five nations thus divided have now set the continent ablaze with the flames of war.

Great Arcadian Empire
The empire that originally ruled this continent, possessing powerful weapons and armies. It is the nation to which the Machina of Saint Island swore their loyalty and knelt.
It is located in the heart of the continent.

Solas Empire
A nation located in Solas, a desolate desert region. Despite poor weaponry and training environments, it remains a strong power due to its massive number of soldiers.
It is located in the northwest of the continent.
