Harvesters

Wraith-like guardians that come from the Tower of the Forsaken, the most feared prison during the Empire.

They are involved in a complex conspiracy (The Harrowing) with Death Positive Industries, Lord Dredd, and possibly others.

A swarm of them attacked Catsby Grande's mansion during the Masquerade Ball. The players dispatched them but not until they sucked the soul out of every living thing around them.
