Coda

He was born with his twin in a world of islands, two bigger ones and groups of smaller ones spread across the world. Sans first memory was the endless blue of waves and scene of salty air and seaweed.
There island was called Coda, where all monsters lived.
Then plagues came, the war followed. A world population crisis, that led to harems? and a spell on there soul so no one could back out. Then the AU crumbled, and Sans or Vibe end stranded in another broken AU heavy with child.
Funk... he should have stayed in bed today.
