Castellan
primary

Icy detachment masking brutal calculus beneath

The Castellan commands absolute procedural intimidation, weaponizing the Citadel’s systems to entrap opponents rather than confront them directly. He seizes the doctored printout as definitive proof, issues a purge order via wrist communicator, then locks the protagonists inside by activating the door’s biometric lock—demonstrating absolute institutional authority even if it risks making martyrs of his foes.

Goals in this moment
  • Secure control of the Matrix investigation by any procedural means necessary
  • Eliminate suspected conspirators and consolidate personal power through manufactured evidence
Active beliefs
  • The survival of Gallifrey’s High Council justifies any measure, however unjust
  • Due process within the Council’s ranks can be manipulated to crush dissent
Character traits
Procedural intimidation Absolute institutional authority Selective misuse of forensic legitimacy

His voice remains steady despite the unfolding purge, displaying the mechanical precision of an institutional loyalist carrying out another routine directive.

Goals in this moment
  • Coordinate with the Castellan to locate and apprehend the Doctor
  • Fulfill the Castellan’s summons to Thalia, Hedin, and Zorac to his office without deviation
Active beliefs
  • Institutional directives must be obeyed regardless of their morality
  • Dissent constitutes treason and warrants immediate enforcement
Character traits
Cold institutional loyalty Mechanical procedural compliance Absence of personal investment
