The City

Underearth Arc

During the Underearth arc of Undertale Rho, the City of New Home was the pride and joy of most monsters. It was a symbol of defiance, as the reason it was founded was because the monsters had stopped fearing humans and had marched forward to the end of the Underground. Not much is seen of the actual city during this portion of time because the protagonist never actually went there. They instead had gone to the Palace.
