But darkness rose from among the trees of the forest as they worked.

No way to prevent it, and the darkness was rising.

The darkness ahead of him rose with every step.

He forced another step, before the darkness rose around him, deeper than the void between systems.

And after that lock, a different darkness rose up and brought them down.

The largely unseen motion down the streets was increasing, a darkness rising with the light.

The darkness was rising, but much was still hidden by the shadows.

The darkness rose like a blast from a volcano.

He could feel himself moving upward, and darkness - the true darkness of night - rising around him.

Pity cast a zone of darkness rising six stories from the tarmac.
