I was startled as a small figure materialized at my elbow.

Trout stopped short as two figures materialized from the darkness.

A weird figure had materialized from a dark corner of the room!

In the darkness ahead the figure of a man suddenly materialized.

Suddenly, at the end of the platform, a figure materialized, moving quickly toward me.

But as she did so, two figures materialized behind her.

Five figures materialized on the pads in front of them.

From the blue gloom of the room a figure materialized.

Just outside the white fire, so close that it shocked her, a figure materialized.

Moments later, two figures materialized at last on the platform.
