While exploring a mountain, you discover a massive hole, though you discover it by falling into it. You fall for what seems like forever before everything goes black. When you woke up, a tall goat woman stood over you with a kind and concerned expression on her face. She spoke to you in a soft and gentle voice, showing concern for you.

“Oh... you must've fallen down here... come with me, my name is Toriel, and I am the caretaker of the Ruins. I will lead you somewhere safe. So, you must follow me.”
