The Denial of Death: The Blackwake use a fusion of shadow-magic and ice to achieve brutal, pragmatic preservation. A Frost-Surgeon cloaks the wound in a field of intensely focused, localized Coldshadow.
Cryogenic Stasis: This instantly arrests all biological decay, infection, and blood loss by placing the damaged cells into a state of cryogenic stasis. The healers do not see this as "healing," but as a preservation of utility. The body must mend itself over time through the recipient's own stoic endurance.
