Cave Lake

The great lake in the cave felt strange everywhere. It was clearly a place like an underground lake, yet there was not the slightest trace of dampness; no moss could be seen, nor any stalactites or stalagmites.

The surface of the lake was like a mirror, unbelievably calm and seemingly boundless. The moment Harry and the others entered, they could feel an eerie silence, and an indescribable oppression.

"Something really is wrong with this place..." Lupin's tone was rather grave. "Even the Wand-Lighting Charm is being suppressed."

Hearing Lupin say that, Harry looked up in Lupin's direction and saw that the light at the tip of his wand had shrunk, dimming greatly until it was only the size of a fist;

The light looked grayish green, as if covered by a layer of mist, and at most illuminated only a small circle around their bodies.

"I've seen the Inferi Voldemort sent into the war. They didn't look like this... These people look as if they only died not long ago... On this person... is that the mark of an Auror?"

As if to see more clearly, Sirius Black braced one hand on the ground, his cheek almost touching the surface of the lake.

Harry's feelings at that moment were extremely complicated. He felt revulsion toward the corpses, toward the Inferi, but also concern for Sirius Black;

When he saw Sirius Black so close to the lake, he still stepped forward, to keep an accident from happening to him.

"It really is an Auror..." Sirius Black held Harry's arm and stood up, his tone rather rueful. "I've seen this Auror before..."
