So I'm curious, what does the Starground look like, and what does Asriel do there when he isn't being Flowey?
The Starryground is full of colors, crystals and it’s like heaven. It’s very childish like, Asriel presents it as a perfect world.
When he comes back from the Underground to the Starryground well, he kinda visits?? He makes sure his “soldiers” did the job he asked.
His place might be really colorful and beautiful, everyone hides from him. It’s common to see piles of dust in the abandoned cities. His “perfect world” is a cemetery.
