They came to a high point in the tunnel where the heavy black mist had not reached.

I could almost see it coming out of me, like a black mist.

"A black mist and chaos force beyond it, going away."

It is described as being a black mist with five eyes.

And already the black mist had billowed over those who were with him.

In the 1950s, while still a young boy, he was blinded by a "black mist" from the south.

The stillness rose like an invisible black mist around him.

He spoke thus: "It is because they know that the black mist will return."

His mind was empty, surrounded by a creeping cover of black mist.

The scent and taste of fear hung like a black mist in the air.
