Levin Cloud brought the Ice Queen Elona to her quarters in the castle and proceeded with the treatment. He actually created a magic circle using his own blood as a way to treat the queen as the poison in her body is from divine origins. The dagger that was used to stab her might be a relic that a dark god is sealed or from a body of a fallen dark god. Either way, Levin Cloud already told them that it will take one day in order to heal her completely and another day for rest.
Levin Cloud even reverted to his original form and called upon the powers of the forest to aid him. A soft viny chrysalis covered the Ice Queen Elona and sapped the poison out from her body. Nature itself responded to her call as if they felt gratitude for her taking care of them. If one looked outside the doors of the castle, the balance of nature and urbanization is well taken care of.
