From publisher blurb:
The Thralls are Coming...Sometimes, a villain needs a little help. Whether it's with Magic, Martial Arts, Mechanica, Powers, or Psionics, they can now summon up that help with a little time and a little Risk. It doesn't matter whether they're zombies, robots, minions, demons, or creations of pure will and imagination; they're called Thralls, and they're coming to make life difficult for the heroes of every era!
Includes two new character packages (Thralls and Demons), new Magic Spells, Martial Arts Techniques, Mechanica Systems, Powers, and Psionic Disciplines for creating, summoning, and manipulating Thralls of all kinds!
Also included are thirty Thralls, including undead, minions, robots, demons, spirits, and the creations of will and imagination collectively known as Thralls themselves!
And who knows? Maybe Thralls aren't just for bad guys any more. Explore the economics of Thrall creation for fun and profit, try a little Necromancy or Diabolism on for size, and decide where you stand on the issue of free will.
Thralls can think and feel, but they're considered property at best. To most right-minded people, that's considered slavery; will you stand back and watch society run on the backs of enslaved intellects, or take a stand for the freedom of every sentience, no matter how inhuman?
Better make a decision soon... the Thralls are coming.
