Andrew had broken through the barrier of the fourth divine seal and obviously, it had a strong manifestation. Not only did he and those close to him receive the bath of the divinity that developed over him, but some other people as well.
As Andrew came into contact with more and more people, his divinity tended to spread to them. Obviously, it wasn't just anyone, but those who were on good terms with him.
In fact, it was more correct to say that his divinity touched everyone who had a close relationship or trust and loyalty with him, such as some employees or allies like the Dunnas royal family or Victoria's family.
Zaros and Elidyr fell into this category. They are powerful and ancient demigods, but they have still treated Andrew with great care and respect, protecting him from any harm.
