Cure.

Valerian finished reading the letter and placed it back on the counter before he started eating the food. He channeled the light attribute mana in his body to heal himself. From time to time he would cast a glance at Fortuna, but the moody princess of dragons was unusually calm. 

After he finished his food, he walked over to check her, but apart from the fact that her breathing was stable, he did not know anything. So he turned to look at the magical bookshelf, however, none of the books recorded anything related to dragons. 

Fallax appeared behind him and said, "Never judge a book from its cover, but you are correct, they do not record anything about the medical conditions of the dragons. Humans have no knowledge about this, Dragons are almighty beings, they do not fall sick. She will not wake up for a week at least. It will take some time to digest that core."
