*I'm just a poor fanfic, nobody loves me* Everyone else writes 'em, so why not? You fall into the underground. A flower is there to greet you. A goat mother is there to care for you. But everything goes down hill when she disappears, and your forced to run. Your sister is after you, and your friends. You have to protect them, but.... Your just an anomoly. What can you do? I've put twists on some of the characters and stuff, so hopefully I don't mess anything up. Also, the cover is not mine. Google is just a great thing to have. I'm sorry I don't know who made it, but if you do, then please, feel free to tell me. (Please read authors note. It has important information.) All characters and the game belong to original maker, Toby Fox.

"Damn you sans...." He cursed under his breath. Sans is late for dinner... again. Papyrus was almost used to this occurrence, ever since he met that little bar worker all he had been doing was running around for her. He didn't understand the need to run around for someone. He personally thought it was a full waste of time, Sans had much more important things to worry and deal with. Not that he hated her, he found her quite nice company. Besides the stupid puns and jokes she's been picking up from sans. One of sans' most said and most irritating puns. "Sorry pal but i gotta' ton of thing's to do.... a SKELE-TON" he was cooking in the little workers kitchen, once he heard that leave her mouth he almost left the place. He most definitely yelled at sans for "staining" the little humans humor. Only to be told he didn't tell her that one. "papyrus!"

'Filled with power the Queen will rise but loving monsters led to her demise. (Y/n), Queen of Darkness' Frisk stared at the plaque and took a look at the tapestry. A girl with spade cheek marks, around her 20s held a parasol surronded by roses. She was accompanied by a monster who Frisk couldn't recognize but seemed oddly familiar. The two bore matching outfits, the girl a short sleeved purple dress with a white undershirt, a cresent moon decorating it. She wore long purple gloves as well. It seemed edwardian. The other wore a dark purple coat and pants. A white sweater underneath. Maybe they were a couple or something. Frisk shrugged at the thought and motioned for everyone to follow them further into the castle, missing Asgore's, Toriel's and Sans' long stares at the tapestry. "Is that....really them?"
