"This is the Deadside, the Wasteland, the nothing beyond the bone-backed gates. Here the true darkness at the heart of all things is made real.
What we see in death's dominion is as void as a dead man's gaze, as cold as the light from a dying star."
The Deadside is a hell-like world and is the main setting in Shadowman. The Deadside is full of the Deadsiders, Zombies and other suffering creatures. When The Shadow Man first arrives there using Luke's Teddy Bear he is to seek out Jaunty near the Marrow Gates to learn the specific gruesome details about Deadside since Jaunty has more literal advice than Mama Nettie because he is trapped there for eternity under Nettie's voodoo controll.
- Instead of being water like in The Liveside everything is pools of blood in The Deadside.
- As mentioned in the 1997 comic when Mike talks to the bartender describing a "skeleton witch woman and a skull headed snake" he thinks Mike is crazy. Jaunty explains since Mike is also the Shadowman he sees things the way his mind wants to see them (through the mask of shadows) but all other mortal men see everything normally.
