Chapter 1: Message in a dream

A twelve year old child named Towki threw her breath to the single candle that sat on top of a piece of bread.
"Happy thirteenth birthday to me," she sighed. After many days have passed since the disappearance of her younger sibling named Frisk, Towki, now thirteen years old and no longer a child, has stopped finding anything worth to exist for. The loss of their parents made Towki vow to protect Frisk now that they were the last thing she had. But now she felt lonely and guilty for making Frisk feel like crap before they disappeared.
Towki held the fake blue dragon tooth charm from the necklace that Frisk gave her two days before their argument and two days before they went missing.
After changing into her red oversized shirt for her petite body and lose gray pajama shorts, she brushed her long brown hair that reached her lower back and tied it into a ponytail. She layed on the bottom bed of the bunkbed that belonged to the orphanage she resides. The same bunkbed she used to share with Frisk.
Her guilt made her think of their stupid argument until she fell asleep.
"Towki... Towki!" a fading whisper called out to her.
Towki looked around but she didn't find anything. She was surrounded by a blue colored atmosphere.
"Towki!"
She finally recognized the voice.
"Frisk?"
"Towki, you have to help us." Frisk's voice was now clear.
"Help who?"
"Remember about the legend? The myth? About the war between humans and monsters?"
"Yes I do. Frisk what's going on? Where are you? I can't see you."
"I only have a limited amount of determination but I will try to make it quick. Follow the instructions that the story says. It's all true. The underground is real. Something has happened to the underground, now it's all... groundUnder. Everything is mixed up because of a glitch and now I can't go further because I'm confused. Help us, Towki. When you land on the groundUnder, the dragon tooth charm will absorb my consciousness. I cannot go back to you but I will guide you to me... And we can both go home. Please... Towki..."
Frisk's voice slowly faded to nothing.
"Frisk! Please don't go! I miss you! Frisk!"
Towki's eyes jerked open early in the morning, liberating her from her dream. Was it real or it was just a dream that gave her the illusion of what she wanted? But if it was real, would it be worth the... Danger?
Towki hesitated at first but the thought of guilt and lonelyness caused her to get off the now used bed and prepare herself for an unknown adventure. An unknown danger.
She grabbed her best shorts and wore them over her black leggings. She took her favorite red tanktop and her red cat ears that she had since she was a child. Before she stepped out, she took her asthma inhaler and a hairband just in case the other snapped on her long, thick hair.
The last thing she had to wear was her favorite black combat boots. She laced them together, secretly made her way to the orphanage kitchen to make herself a sandwich for breakfast, and finally walked out the door.
"I'm coming, Frisk." she said when she finally found the opening to the groundUnder.
What will Towki do?
A) jump
B) climb down
C) look down to see how deep the fall is
