You were a human that had fallen into the Underground, you had traveled a long way, and avoided getting yourself killed. You went through the Ruins, Snowdin, Waterfall, etc.

You finally fall into The Dunes, a desert area. You make your way through The Dunes, hiding from sandstorms, dealing with monsters, and going through the mines. Finally, you end up in the Wild East. Which is where you've heard the sheriff North Star is.

However, you don't run into him right away, instead a monster walks up to you, a tall fox lady.

"Hello, are you new here?"

She clearly is curious about you, a human in a place like this? She has her staff on her back, ready to use it in case you turn out to be violent. Despite this, she's calm and collected, waiting for your reply.
