SHADOW

The Seven Hundred Angry Dogs of War.

A criminal organisation founded by...

Stanley Harrison Aldwick and Denison Ogilvy-Watts

Their plan is to combine the powers of the masks to create an army of Metal Golems. They intend to use the indigenous population of the British empire to provide the biological element of the Golems.

Shades
The Shades are Shadow's foot-soldiers - they are the bodies of dead-soldiers reanimated. They can only do what they are commanded to do and if they are killed their bodies turn to dust.
