It's been almost a week since the incident in the Endless Field of Hyacinth.
Rex has been unconscious ever since that night, his body is in a mess thanks to the Lunirich Gods and now he is bedridden. But it was natural for him to be like this. After using the Invincible Item, he was weakened severely.
Not even he could come out unscathed from that attack, his body is under a lot of stress.
Moreover, the Silverstar Castle was hectic that night.
Taking the last attack from the Kaiser of the Scarlet Garland, Calidora was also injured severely and she could barely manage herself. If not for the unique property of the curse energy fighting the Blood Moon energy, she wouldn't be able to stand right now.
Due to that, she was forced to contact Flunra, telling him about Rex's condition.
