A/N Just a story that has been bugging me for a while now so I decided to put it onto here. I hope I don't disappoint!
Frisk and Chara are twin sisters. Frisk is mute and Chara protects Frisk as best she can but Chara is finally fed up with humanity and climbs Mt. Ebott with Frisk right on her tail...
Frisk tore up the mountain after her twin sister, signing rapidly for her to stop. Chara doesn't see her signing and keeps rushing towards the top of the mountain, yelling at Frisk to give up.
'Stop Chara, please... if you leave...' Frisk though as she dodged another branch that was swung towards her in her sister's wake. Both of them were running out of breath, but their determination allowed both of them to continue up the mountain.
Chara was determined to escape it all.
Frisk was determined to stop her sister before it was too late.
Chara finally slowed down as she reached the top, but tripped on a root sticking from the ground. A scream tore from her mouth as she slid the small distance towards the gaping hole at the top of the mountain. Chara scrabbled at the small ledge stopping her from dropping into the mountain's depths. Chara can feel her hands start to slip, but held on anyways. Climbing this mountain didn't feel like a very good idea anymore... Chara felt the ledge give way under her weight and gave a scream for help. 'But nobody came...' she thought as she began to fall.
Suddenly, a hand grabbed her wrist and her sister slid into view. However, the ground was unstable and both of them began their fall into the mountain. Chara had one though as she fell. 'Except my sister...'
Frisk sat up blearily as sunlight streamed onto her face. 'Where am I?' she thought as she slowly sat up, rubbing her eyes. Frisk stood up and took in her surroundings. She and her sister had landed on a patch of golden flowers that somehow broke their fall. The walls were covered in purple brick and there was a door at the far end of the hallway. Frisk quickly looked over her sister, searching for any injuries on her sister. There were none that could be seen, but she was worried anyways. Chara had taken the brunt of the fall and hadn't woke up yet. Frisk slowly walked down the corridor and through the next few rooms, trying to find someone who could help her sister. There were random switches and one extremely long hallway, but she soon came to a bowl on candies. She smiled and took one, stuffing the sweet into her pocket to give to Chara later.
Frisk turned around and walked down the hallway she hadn't gone down yet. Suddenly, the floor broke from under her and she fell for the second time. Frisk banged her head on the ground and everything grew fuzzy. 'Gotta... help... Chara...' she thought just before passing out at the bottom of the pit.
