After Seraphine met the dragon god Seid and learned a little more about the imperial family from him, she let Eric do his thing and take the lead from that point on.
Apparently, he prepared a welcome party for her - a kind that she did not expect at all. He first treated her to yet another nice meal which was more like a grand banquet than a simple dinner, and after that, he took her to a tour around a certain part of the castle. As much as he wanted to take her all around the palace, he could not for several reasons.
"One of them is that I have yet to deal with the consequences of taking you here. Once the others found out that I brought my lover in my place, they would not let me hear the end of it. But there's no need to worry. I'll handle it. Another reason is that I can't spend all day touring you around. I still have one last surprise for you," was what Eric reasoned out to Seraphine at that time.
