The healers were transferred through the portal to the second region of the Arcade mansion, which was under Arnold's charge. Due to security concerns, he had not been able to return there, hence he was still living in his father's mansion.
Upon arrival, the healers quickly rushed Arnold to the medical ward where they placed him under a magical barrier even greater than the previous one. This barrier had been constructed by the previous Lord of the Arcade family household, a very powerful mage who had used his ice magic to create it. The barrier was unbreakable to mages below EX Rank, providing a formidable layer of protection around Arnold.
