"Oh, our poor child! What could have taken him so quickly?" Lady Toriel, Queen of the Underground, was sobbing into her hands. Her adoptive son, Chara, had recently fallen ill and died. Asriel had taken him to the surface, and hadn't returned.
King Asgore was searching through the boys' room, and pulled a dresser drawer on Chara's side. He pulled out a small vial, and popped the top, sniffing.
He flinched as a strong smell of buttercups reached his nose, and he went into shock.
"Your majesties!" Undyne suddenly burst into the living room, as Asgore turned around.
"Where's Asriel?" Toriel cried
"Mommy? Daddy?" Asriel cried out to his parents, as they placed their hands on either side of him to comfort him.
"My baby?" Toriel asked, as he smiled.
"I don't feel... Anything"
And with that, he disintegrated into dust.
Sweet Lord, this is something I had to pull together last minute. I thought Asriel's death could be the kick start to this story, which could go about anywhere. Chara (its a definite he in this story)has something to do with this, I swear!
I do think he/she committed suicide, because that's just what they'd do. Buttercups are extremely poisonous, and therefore, since Asriel is now a buttercup, it would make since
This is pulled from a shot comic strip called "That's rough, buddy" so I claim no ownership to this prologue plot, or Undertale itself. But I do claim ownership of the plot for the rest of the story (somewhat)
