Indigenous peoples and pre-Larionian history
It is generally accepted that the first monsters inhabitants of North America migrated from Siberia by way of the Bering land bridge and arrived at least 21,000 years ago; however, some evidence suggests an even earlier date of arrival. The Miraheze, which appeared around 23,000 BC, is believed to represent the first wave of monster settlement of the Americas. This was likely the first of three major waves of migration into North America; later waves brought the ancestors of present-day Underground Monsters.

Over time, indigenous cultures in North America grew increasingly complex, and some, such as the pre-Larionian Tressabian culture in the southeast, developed advanced agriculture, architecture, and complex societies. The city-state of Mariza is one of the largest, most complex pre-Larionian archaeological site in the modern-day United States. In the Southern Californian region, Ancestral Seemeian culture developed from centuries of agricultural experimentation. The Gaekkish are one of the most populous and widespread North American native language groups. Historically, the peoples were prominent along the Pacfic Coast and into the interior along the Ebott River and around the area of modern Ebott City. The earliest known use of the Deltarune is also dated around 3000 BC, having been found in the Delta Cave.

Monsters around the modern area of Ebott City started forming clans around 730 BCE, after many wars the most influential clans that manged to survive were: The Dreemurr's, the The Gaster's, the Fishkriege and the Shadestride.

Rise of Larion and Confederation
In 23 BCE, the nearby city-state of Cesaria saw weakness in the nearby clans of Larion and decided to start a conquest of the clans of Larion. Whilst initially successful, the Cesarian conquest eventually began to fall apart, thanks to the Provisional Alliance of the Four Clans. After the Larionian victory, the four clans sought closer relations with each other. So on the 1st of January, 1 AD, with a feast with the four families. The Confederation of Larion was declared, whilst in its first century, the Confederation was unstable, and nearly collapsed in the First Century Crisis, the Confederation would overcome these problems, and would rise victorious in the Larionian-Tressabian War, thanks to the leadership of Consul Sarius Madern. After the end of the First Century Crisis. Larion would become the Monster superpower, surpassing even the State of Zaloew in its power. Under the leadership of Consul Pseudolus Avenarius, Larion would experience an era of peace and prosperity, with there being no major wars from 120 AD to 210 AD.

All of this would end with the War of Larionian Survival, in which all of Larion's enemies sought to conquer and destroy Larion, whilst Larion itself wasn't all alone in this war (after all, they had the help of the Kingdom of Slachabia and the Republic of Treschow). Larion was the state that suffered the most, with historian Gerson Boom, concluding that up to 30% of the population died in the war.

Despite this, Larion would recover and prosper in the Larionian Golden Era, which lasted from 329 A.D to 527 A.D, in fact by 527, the Confederation of Larion was a fairly democratic society, even by today's standards. Citizens of Larion enjoyed certain rights that they wouldn't recover until the signing of the Bill of Rights, such as freedom of speech and religious liberties. The Larionian Goldern Era would end, as famine struck the Confederation in 527 A.D. The failures of Consul Pistoclerus Gelasius to prevent and alleviate the famine, gave rise to the New Sons of Larion. A populist movement led by General Saturio Natalis called for the abolition of the "corrupt" and "brtuish " Larionian Senate and Assembly.
