All the gods reached the heaven, going straight to the God of Foresight, who lived in his own palace in the heaven.
The God of Fortune didn't live alone like most gods. He didn't keep servants either. Instead, he lived with his students who learned under him. As for the students, they weren't from heaven either.
Instead, he preferred going to different worlds and finding different people who he believed had the talent to learn his art. It was all because he didn't have a kid, and he wanted to find someone to inherit his Foresight so that this art never disappeared.
Even though other gods didn't like the fact that the God of Foresight was meeting mortals to heaven, he kept them in his place and didn't let them leave. The students didn't know that they were in Heaven either.
On the promise that he was going to keep the kids in his Palace and wouldn't let them know about the heaven and the gods, he was allowed to keep them here.
