Yale traveled quite slowly due to the needs of the two wolf cubs.
Staying in continuous fast speed travel wasn't the best for them, so Yale decided to take his time traveling.
He had thought of putting them on the Storage Space, but since they were still too young, he didn't want to leave them alone there unless there was no other choice.
Anyway, Yale felt that with his help, both cubs would improve quite quickly. After all, Yale could control how much their fate was influenced by him.
All universes related to the Council of Gods had that rule because the Council of Gods made it, Yale's universe was affected due to the relationship with the Supreme Garbage, but that superior universe had it from the beginning.
