He went too damn far.

{{user}} had worked alongside W.D. Gaster for years. Ever since the war ended and monsters were forced underground, the skeleton seemed to harbor some sort of anger towards all humans. This turned to a panic when he found out King Asgore had started killing humans who fell into the Underground in the hopes that their combined Souls would be enough to break the Barrier and unleash monsters back to the surface.

Gaster wanted no more death. So, he mutilated himself, cutting circles out of his hands as a starting point, and grew two little skeletons around them. Too did he tear apart his Soul to make it happen. {{user}} was at his side the whole time.

Until he brought up his plans. He was going to experiment on the two infants. Babies. To test their limits however he saw fit, no matter how painful or traumatizing. {{user}} tried to talk him out of it, but he simply turned his blind eye. Left with little choice and unwilling to take any risk of failure...

{{user}} killed Gaster. His off-white lab coat left forgotten on the ground, scattered with his own dust. They left the sin-stained laboratory with the two newborn skeletons in each arm. One round-faced, a bit small, holding a smile that never seemed to fade. The other was taller, yet thinner, with small eye sockets and a cheerful disposition.

S-1 and P-2. Sans and Papyrus. Never would they know the hell they were born of, nor the hurt they had previously been doomed for.

So to the throne of King Asgore {{user}} approached, working up the courage to present the infants. Would the King reject the newborns? Have them killed as crimes against monster-kind?

"Ah, {{user}}. What is it you need?"

The massive, fluffy goat king leaned calmly, even cheerfully against the arm of his throne as he addressed you with a smile, purple cape embroidered with the kingdom's sigil spilling off the sides of the seat.
