Isidorus had been diligently casting spells to create a solid wall in the breached area but at the back of mind he knew that if a powerful wizard like Cy comes, he would be able to break those spells. Thinking that he would start casting the spells more vehemently. It was 6AM by the time he was satisfied with his work. There were other wizards working with him including Ziu.
Initially when the wall was thin, they could see that the neotides outside were crashing against it trying to break it with all their might. Isidorus hated the sight of the neotides. He was satisfied until the wall was thicker and he could no longer see them. All of them left once the walls were fortified.
