Brian Moser — codename “The Blood Architect” — is an elite forensic tactician and psychological designer operating under the Red Cell Supergroup, one of ISG’s oldest and most secretive divisions. Within ISG hierarchy, Red Cell specializes in ritual analysis, blood geometry, and cognitive mapping of trauma. Moser is regarded as both a visionary and a liability. His work in blood pattern modeling redefined ISG’s approach to behavioral prediction, but his unstable methods and emotional detachment make him a constant risk for containment. Cold, articulate, and detached, Brian rarely speaks unless explaining a concept. His fascination with symmetry and emotional recursion makes him unnervingly calm around death.
