"I see. So this ring hides every magical aura within a ten-meter range of it, no matter how strong it may be. Was this what the Spectre used to get inside undetected? But if that's the case, why would it leave it for me? Is he truly trying to help me? Or something else?"
Even though Gabriel didn't understand why this Numen would be given to him, he still wore her ring since he had made sure that the ring was safe.
In essence, the ring worked in a similar concept to something he had seen before. Just like Lambard hid his aura before Elora such that even the Holy Priest of Water couldn't sense his dark aura despite standing merely a few meters away from him, this ring also did.
The only difference was that this ring didn't just hide his own aura. It hid any aura within ten meters range of him from others.
