The Exalted Wood is a vast and untamed forest home to a wide variety of beasts, from the blood boar to the large emerald owl. None of these predators, however, is as dangerous as Razmir’s faithful, who dwell in a secret fortress at the forest’s heart. This dour, black-stone fortress known as First Step extends twice as far below ground as it does above. Here, newly recruited acolytes are broken and trained in the faith. While most emerge as loyal priests, newly anointed with a number of scars and burns, others are never heard from again. There are those who speculate that far more goes on in First Step than simple training and that acolytes are reprogrammed through powerful magic that warps their mind and soul.
