Gasters story. As of now.
Once upon a time a scientist was here.
The most brilliant and strongest monster the underground ever had.
Able to kill a person in seconds.
And so. So much determination.
They could reset. Save. All the fun things.
Until one day. A child fell.Chara.
The demon that comes when people speak it's name.
Gaster trusted the child as well. With his life.
And all was well. Gaster made the core.
The source of power for all the underground.
But with this dark force of matter awoken something outside of mortal worlds. Void The void liked this place. So peaceful. And kind.
It wanted to destroy it all.
It invaded the poor child's mind until they inevitably went insane.
Calling the void their "master" and doing anything it asks.
First. They killed gaster. Pushing him into his own creation. Then they killed their own brother in cold blood. There they sat. Sitting there laughing stabbing the young child.
The queen and king were absolutely mortified.
They killed the poor child, trying to calm them down.
But failing in the end.Back to gaster. They had fallen right into the voids clutches.
He was terrified. Of what. Of who he did not know. Of course. The void showed itself. Opening 3 eyes to look at the scientist.
After core
The void killed him. Over and over. And over again. The scientist fought back for 3 days. Against the primordial God.
But dark does not tire. Dark does not relent.
Even in the light there is shadowThe scientist. After 3 centuries of suffering fell back into reality in pieces. 14 of them.
Across a few aus that I can't name.
He went more crazy in thereFrisk fell and the player did genocide.
Chara was into it. Absolutely happy with all of it. "One left."
"35 left."
"0 left."Chara appeared. And did their speech. Stabbed frisk. But instead of sitting there ten minutes like normal...the void was there to meet them.Their death was inevitable.
The player never picked the game back up. Softlocking the poor monsters.
What very little determination that was in the vessal, and their body dropped from the void.
Gaster absorbed the soul and broke out.Gaster was influenced by the dark right off the gate. Looking for the chara that did what they did to him and asriel.
But failed.
They-for their loyalty- was protected by the void. And this is the story we know so far.
