The Deltarune of Scarlet Forest is a mammoth, socially progressive nation, notable for its barren, inhospitable landscape, absence of drug laws, and spontaneously combusting cars. The hard-working, democratic population of 5.649 billion Scarlet Forestians live in a state of perpetual fear, as a complete breakdown of social order has led to the rise of order through biker gangs.

The relatively small, liberal, pro-business, outspoken government prioritizes Defense, with Welfare, Healthcare, and Public Transport also on the agenda, while International Aid and Spirituality are ignored. Citizens pay a flat income tax of 8.7%.

The strong Scarlet Forestian economy, worth 185 trillion Dark Dollars a year, is led by the Woodchip Exports industry, with major contributions from Automobile Manufacturing, Tourism, and Furniture Restoration. Average income is 32,793 Dark Dollars, but there is a vast disparity between incomes, with the richest 10% of citizens earning 211,357 per year while the poor average 2,055, a ratio of 102 to 1.

Crime is a serious problem, with the police force struggling against a lack of funding and a high mortality rate. Scarlet Forest's national animal is the tasque, which can occasionally be seen sifting through garbage in the nation's cities.

Scarlet Forest is ranked 181,634^th in the world and 164^th in Link to the FUTURE for Most Compassionate Citizens, scoring 42 on the Kitten Softness Rating.
