Eiro slowly stood up, his body heavily slowed down due to the extremely cold temperatures he had been exposed to for the past few hours. At the very least it seemed to have worked, and Eiro's fury disappeared for now. That didn't mean that he wasn't angry about this whole situation anymore, just that he didn't need to worry about losing control as easily anymore.
And so, for now, so that he could properly get rid of the side-effects of freezing his body to temperatures that would kill anyone else, the Demon stopped pushing Ice Magic into the runic carvings and instead used Fire Magic.
