Albion saw nothing wrong with letting Yemina, Yule and Blake continue to live their regular lives. If Blake wanted to buy food from the town or hunt, with his power no one in the town could stop him. Yemina was in good health and the baby inside of her was growing well. Yule didn't seem harmed by her encounter with the parents of the children she tried to make friends with. While she might have been a bit fearful of adult humans now, she was going to be fine. Albion had no reason to do anything else. He could only tell the Adventurers Guild later about the situation he found.
Advising those high-ups to leave the nice family be. While many were against letting demons live so freely, viewing them as dangerous beings that could bring destruction at any moment, Albion knew those who agreed with his peaceful views. Especially Arthur, who was in charge of managing the affairs with the otherworldly beings and thus, was closely related to the Adventurers Guild.
