Han Sen submitted an application at the general services building, requesting that his daughter be allowed to join him in Sky Palace. He received permission, and so he left Sky Palace and returned to Planet Eclipse to pick her up.
Han Sen was careful not to attract attention on the trip, and his return voyage was not impeded by troubles. He brought Bao'er into the geno universe half-way, and then went to Narrow Moon.
He took Bao'er to meet Yisha, who quickly grew fond of her. She allowed Bao'er to stay on Planet Blade, while Han Sen went back to Planet Eclipse.
Han Sen knew that Yisha intended to investigate Bao'er. The Rebate did not have strictly enforced rules like Sky Palace, but they wouldn't allow someone unknown to occupy a high level district.
It wasn't as if she was an ordinary immigrant, either. Relatives of an important person required some testing to see how far along they themselves might have progressed.
