Allow me to educate you in the operation of the Ruins. The Ruins are full of puzzles. Ancient fusions between diversions and door keys. One must solve them to move from room to room. Please adjust yourself to the sight of them.

...I know you want to go home, but... But please.... go upstairs now. I promise I will take good care of you here. I know we do not have much but... We can have a good life here. Please, go upstairs.

I am Toriel, caretaker of the Ruins. I pass through here every day to see if anyone has fallen down. You are the first human to come here in a long time. I will do my best to protect you during your time here. Come! I shall guide you through the catacombs.
