As Rio reached his room, he made sure to warn the guards outside that no one disturbs him for some time, and not to let anyone in. This'll be the first time he would try to call for some God and he had no idea how long it would take. Considering that Skuld's attention was still on him, it shouldn't be hard to call for her, and seeing how she was angry at him for lying about her and needed an explanation she should be easy to call for. But who knows?

****In Arcadia every God, like in every other world, had the power to listen to the prayers directed at them. While they usually just ignore them as petty begging of mortals, always asking for something or complaining about something, sometimes they do listen and reply.
