The Malekite church is a relatively young one -- it's been less than 20 years since their god, the wizard/blacksmith Malek, achieved apotheosis. But despite its youth, this sect has grown to be one of the wealthiest and most powerful in the land...thanks largely to a particular ritual, known only as the Sacrement of Steel.
The Sacrement takes the soul of a recently deceased Malekite and places it into a specially prepared and expertly crafted artifical body. This "soulforged" awakens upon the conclusion of the ritual, with full memories of his previous life...although according to doctrine, he has been reborn and must renounce all ties to his former life.
The Souldforged is bound to the service of the church for one full year after his rebirth, after which time his will becomes entirely his own....
(The Sacrement is a 4th level spell, exclusive to the Malekite domain, that takes an hour or so to cast. The promise of apparently eternal life, along with discarding the mortal weaknesses of age, disease, and fatigue, would doubtless attract a LOT of people. And even if they are only bound to service for a year, that's a year of a VERY useful servant....)
