Navigator

The Navigator is a sanctioned mutant and noble scion of the Navis Nobilite, tasked with steering the Ignis Aeternus through the warp using the Warp Eye, a unique genetic mutation that allows perception within the Immaterium.
Holds absolute authority over the vessel’s warp translation, course plotting, and Empyrean navigation.
Operates independently from the chain of command—answering only to the Lord-Captain and the broader interests of their House Navis and the Adeptus Terra.
Has final say over when and where warp translation may occur, overriding all other officers when warp conditions become dangerous or unpredictable.
Maintains privileged access to the Navigator’s Sanctum, a blessed and shielded chamber atop the command spire, where no unsanctioned personnel may enter.

Plots warp routes by perceiving the Astronomican, the psychic beacon projected from Terra, using the Warp Eye.
Steers the vessel across warp translations, through warp currents, and around daemonic disturbances, ensuring safe translation between stars.
Interfaces with astropathic relay data, Imperial cartographs, and the dynasty’s private warp charts, often provided by the Master Helmsman or Seneschal.

Supervises all warp jump initiations, ensuring proper ritual compliance, Gellar Field readiness, and psychic safety of the crew.
Guides the ship during translation emergence, preventing catastrophic re-entry, misalignment, or breach into realspace anomalies.
Advises on warp tides, immateric weather, and windowed safe zones for optimal transition timing.

Acts as the ship’s first and most sensitive sensor for disturbances within the warp:
- Daemonic presence
- Psychic turbulence
- Warp echoes or false Astronomican trails
Collaborates closely with the Warp Channeler, Mistress of Shields, and Enginseers to ensure Gellar Field alignment and psychic insulation during translation.

Represents the interests of their Navigator House, which is bound by ancient contract to House von Ulm or operates under temporary mutual oath.
May serve as an advisor on warp route trading, navigation treaties, or privileged travel corridors under the control of the Navis Nobilite.
Maintains records of secret or partially classified warp paths, which may be bartered, protected, or sold as assets of strategic value.

The Navigator is not part of the military command structure, and cannot be overruled in warp-related matters except by explicit Inquisitorial authority or direct command from the Lord-captain.
Due to their psychic nature and sensitive physiology, Navigators are protected at all times by dynastic guard, and possess personal chambers isolated from unfiltered warp presence.
