A single beam of light flowed like a river into the office, gracing the smoothen pine desk, the colour of chocolate. As always, soft snow was drifting peacefully outside, like dust falling from a windowsill. Age-worn pines stood like sentries, as if guarding this once-prideful land from those who sought to cleave it. Amongst the office were papers, faded in print but in no means falling apart, scattered across the tranquil room like fallen leaves upon a forest floor — not that the forest here was oft carpeted in such a manner; there was always endless snowfall, hailing from some point above. It was oft easy to forget that one was indeed not on the surface — the cavern that held this wintry space was far beneath the ground, yet it was so vast in kind that the ceiling stretched beyond vision, and a glare of something-or-other always obscured what little one could see of the rocky roof. It wasn't like this in all places, but here, in the heart of Snowdin, one was not reminded of their imprisonment beneath the earth. Perhaps that was why tourists so commonly flocked to this place; a habit of the wider populace that gave easy income for the leaders of Snowdin.
The leaders...
One of which was within this very office.
Her name?
Muffet.
It's not finished...an update will come later. 
As she contemplated her finely furnishings, Muffet stood to leave. Turning the ornate golden doorknob, she strode past the quaint wooden hallways, past the watercolour paintings of past mayors — her predecessors. Striding past the gilded stone-set door, lined with gold, she went for a stroll across the snow-covered forest. As she treaded the path of snow, her thoughts wandered. She found herself thinking about the former royal scientist — the one they called . He had aided her — actually, far more than that. After a great calamity had struck her tribe 34 years ago, her family had perished; all of them slain in one fell swoop. She was 2.
But she would not be left to fend for herself, if that had happened, surely she would not be living now, thinking these thoughts. No, instead had taken her in as a daughter, and raised her. On the night of the accident, she had taken her car as soon as she heard, the phone still on her ear while she sped towards the lab, nearly crashing into another car (luckily they swerved out of the way).
Of course, she was too late, and all she could do was mourn. It was then that she made a vow to
eventually landing her the glamourous role of mayor. But even so, her vow, and the secrets that emerged from it, remained unsettled.
Today, however, everything would change.
A frantic civil servant, clutching a slightly-worn piece of paper hurried towards her.
"Ms. Mayor! Ms. Mayor!"
Cecil always had a habit of calling her that. He adored politics, and aspired to one day become mayor of someplace, maybe even his own town. Loyal in nature, he was one of Muffet's most eager staff.
"Ahh, Cecil. I've told you before; you can just call me Muffet."
"Sorry, Ms-I mean, sorry Muffet."
"Fuhuhu, nothing to apologise over. What was it you came to tell me?"
"They said a human fell down! And they're coming here! To Snowdin!"
"...Who told you this?!"
"The scouts did, look, they even wrote a letter!"
And it was true. Clutched frantically in his paw was an official letter, signed by only the most trustworthy scout known to the Snowdin patrol.
The simple fact that they had claimed this, and that it was indeed not all a prank, was already enough to turn Muffet's day upside-down.
What happened next would make her life follow suit.
To be clear, this is the brother of the girl who walks her brother like a dog. Aged up, of course. (You can't see the tail because its at the back)
