Guns and gods

As Shiva's figure suddenly became visible to all, the various fights came to halt for a second as everyone took notice of his presence. Seeing which side had gotten their reinforcements already.

But after waiting for a few seconds when no one else appeared, the fights continued. Since he had no hood covering his face or body, the Nishkal family guard didn't attack him. Thinking he was some guest or someone else, but not their enemy.

But the members of evil's scion who were guarding the teleportation circle sent one of their trainees forward to kill him. Not willing to take any chance, as they couldn't sense his mana or aura at all.

He looked just like a normal unawakened mortal, but with how he appeared no one would believe that, so the answer was clear. A treasure or technique that can cover his body and energy signature.
