Capítulo 564: The Snow Kingdom Princess

A relieved sigh escaped Jen's lips. "But I truly find it strange the level of restriction in the Mist Kingdom. It is not just the books but upon entry at the gate they conduct  some type of magic trial." Jen pointed to a small mark on her fingers. "This dot is a prick from the trial since they had to use my blood, and this is my proof of entry." She pointed to a familiar seal on her palm. 

'I have heard of this since I asked Kazuya about the mark on his hand before, but strange enough I have not seen it on Rhys.'

"Does it have any weird effects?"

"Not that I know off. But ah, it seems to have something to do with the air in the Mist Kingdom. It seems the mist here can be very harmful at night for the residents, even more so for an outsider. This magic mark is supposed to contain properties to conceal that will make it easier for us to breathe in."

She supposes that makes sense.
