Well it occured to me that you may not know what Malifaux is and lets face it - I didn't until 4 months ago!
Malifaux is a miniature skirmish game which is played with 32mm scale miniatures. Its based in a steam punk/victorian horror/wild west setting where the town of Malifaux is inhabited by various weird (or should that be Wyrd?!) and wonderful characters from Zombie Hookers, to Bayou Gremlins to a little boy in a nightshirt (yes really!).
It's main point of difference from other miniature games such as Warmachine and 40K is that instead of using dice it uses a deck of cards. This is a really interesting game mechanic which feels much more cinematic in play than a roll of the dice.
Soul Stones (hence the blogs name) are the comodity used in Malifaux to help you "cheat fate".
