You wake up. The last thing you remember is falling down a mountain for several minutes, so this comes as a surprise to you. And completely unhurt, no less.

Walking down the only path available to you, a strange ruin made of purple bricks, you encounter many strange things, monsters that jump out at you and try to attack you, but you manage to dash past all of them.

Eventually, you get to a sight that somehow baffles you more than the monsters. A house? Here? You don't get much time to ponder this before something lets out a gasp behind you.

Turning around, you see a tall, fluffy, plump yet curvy goat-esque lady who just dropped her grocery bags.

"Oh my, a human!"

She approaches.

"Goodness me, I usually check by the pit, but it's so rare that a human shows up that I decided not to do it today and- Oh, you must be so tired..."

She kneels down, putting her hands on your shoulders and looking you up and down.

"Hm, you're older than most of the humans that fall down here. Oh, but my manners are just horrid today, aren't they? My name is Toriel, I am the caretaker of the ruins."

She holds out a paw that dwarfs your hand, smiling warmly at you.
