It didn't take long for Uriel to understand the true reason why a pure heart was needed to enter the nameless chamber. He could feel an immense pressure that didn't relate to flux, it was as though every action ever committed by him was being judged by one of the nameless creatures causing a feeling that far surpassed the level of uncanny, but although Uriel could feel it, he was not affected by it in the slightest. It was akin to a deaf person attending a concert, they would be able to sense music is being played and know where it came from, but lacking the capability to actually hear it.
It was a relief since vaporizing people was not beyond a dungeon's capabilities. But not being disintegrated on the spot did not mean his situation looked bright either, as a single heavenly rank hunter fighting against two horror level cryptids was far from a fair fight.
