We push inward, toward a small oleaginous black mass suspended in midair—an Obscurus.
Jacob, intrigued, moves into the snowscape to get a closer look.
The mass continues to swirl, emitting a disturbed, restless energy. Jacob reaches out to touch it.

Can someone please tell me what this Obscurial—Obscurius thing is? Please?

I met one in Sudan three months ago. There used to be more of them but they still exist. Before wizards
went underground, when we were still being hunted by Muggles, young wizards and witches sometimes
tried to suppress their magic to avoid persecution. Instead of learning to harness or to control their
powers, they developed what was called an Obscurus.
TINA
(off Jacob’s confusion)
It’s an unstable, uncontrollable Dark force that busts out and—and attacks . . . and then vanishes . . .

Um Obscuro (plural Obscuri) é a criatura, um Obscurial é a pessoa que a hospeda (por exemplo, Credence é um Obscurial, a irmã de Dumbledore é provavelmente um Obscurial etc. a própria criatura, na bolha, é um Obscurus).
