Anatomy of a False Saint

I woke up in a cold stone cell, my body aching and my mind reeling with memories that weren't mine. On Earth, I was Dr. Alistair Finch, a molecular biologist. Here, in the Dominion of Vorok, I am Rhys Volkov, a disgraced acolyte of the Sanctified Synod. The Synod rules this world through miracles - 'gifts' from the goddess Vexia, bestowed upon the faithful. But when I analyze their 'divine blessings,' I see only biochemistry and cellular manipulation, a natural system disguised as faith. Branded a heretic for my inquiries, I am sentenced to the Penitent Mines, a death sentence for anyone, especially the frail man whose body I now inhabit. To survive, I must turn my scientific knowledge into a weapon. Using rudimentary chemistry, I can replicate their 'miracles,' creating explosives from prayer reagents and antidotes from blessed herbs. My quiet rebellion attracts unwanted attention, including that of a conflicted Synod Inquisitor who sees both blasphemy and terrifying potential in my methods. But the real Rhys Volkov had secrets, and as I uncover them, I realize my very existence is a heresy that could either save this world or burn it to the ground. How can I start a revolution when I'm not even sure who I am?
