Trapped behind the barrier and fearful of further human attacks, we retreated. Far, far into the earth we walked, until we reached the cavern's end. This was our new home, which we named... "Home."
A book found in Toriel's Home
Home is the first city of monsters founded in the Underground after the war ended and monsters were trapped behind the barrier. Home was later abandoned when monsters moved into New Home. Home can be seen from a room near the end of the Ruins. The city is inaccessible to the protagonist, but a nearby Froggit mentions that Toriel was last seen bringing groceries from it to make a butterscotch-cinnamon pie.
The Toy Knife can be found in the balcony overlooking Home.
- "Fearing the humans no longer, we moved out of our old city, HOME. We braved harsh cold, damp swampland, and searing heat... Until we reached what we now call our capital. "NEW HOME."" - MONSTER HISTORY PART 4
