Tobias Luttero

Dr. Tobias Luttero

NuCaloric entomologist and xenobiologist aboard the UESC Marathon; designed and conducted the first systematic study of native Tau Ceti IV ticks and originated the tick milk food program for New Cascadia’s colonists.

What the source establishes — canon

Identity and role. Dr. Tobias Eleazar Luttero held the prospective role of Xenobiologist (entomologist) on the Marathon mission, sponsored by NuCaloric¹. His corporate behavioral assessment characterizes him as “generally compliant and amiable unless projects are under-resourced” and “unlikely to engage in social or political agitation”¹.

Pre-expedition publications and grants. His listed credentials at the time of mission vetting include three works: “Longitudinal impact of managed cicada farms on post-famine populations” (NuCaloric Agriculture Annual Review); a UESC Traveling Scholar Grant study titled “Behavioral optimizations for ecopod termite farming” (as Principal Investigator); and a NuCaloric Micro-Environmental Grant study titled “Minimal ecological footprint of genetically modified Melophorus bagoti formicaria”¹. These establish him as an experienced applied entomologist focused on insect farming, gene-modified species, and post-famine food systems.

Mission vetting: three infractions. His pre-expedition profile records three infractions prior to mission approval¹:

1. Minor salary fine for unauthorized modification to common-area incubators.
2. Temporary suspension of laboratory access for removing pupae from a shared vivarium without authorization; upon investigation he admitted to cultivating the missing pupae in his domicile, citing concern for their viability.
3. Temporary quarantine for feeding non-authorized organic fluids to larvae during a backup laboratory power failure; he willingly submitted to quarantine when power was restored.

Sponsor statements. His doctoral advisor, Dr. M. Xiong, stated: “Dr. Luttero’s inclusion increases my confidence in the colony’s first decade, when survivability is the most precarious.” Regular collaborator Dr. F. Ashley wrote: “Toby tries the weirdest things. Send him already.”¹ His candidacy was approved with no objections¹.

Tick Ethogram (Colony Era). Luttero authored an ethogram of native Tau Ceti IV ticks, reconstructed from automated backups after the initial observation equipment and data storage medium were consumed by the ticks themselves². The ethogram covers solitary ticks separated from nests by at least 30 meters and documents nine behaviors²:

• Alarm (A): high-pitched sound emitted to deter predation. Classified Defensive.
• Approach (Ap): rapid straight-line movement over the shortest distance to a target. Classified Aggressive.
• Chasing (Ch): pursuit of a moving target for at least 10m with no regard for the tick’s own survival. Classified Aggressive.
• Foraging (F): consumption of very small quantities of a novel environmental object; edibility criteria unknown; no observable investigatory behavior prior to consumption.
• Retreat (R): logically inferred but never successfully observed in the field. Luttero’s footnote notes he must withdraw from visual contact before the tick does, due to sudden surges in aggression².
• Roll (Rl): soft-body nymphs curl legs against abdomen like a millipede. Classified Defensive; only observed in nymphs stranded outside a nest.
• Singing (S): inaudible to humans but detectable by audio sensors; provokes solitary ticks or nests within hearing range to chase a single target. Luttero footnotes uncertainty about why ticks do not encircle targets the way ants do, calling it “possible evidence against eusociality”².
• Threat Display Abdomen (Tda): tick moves abdomen side to side. Classified Aggressive.
• Waving (W): tick ceases movement, lifts each leg in succession, and rotates it counterclockwise. Purpose unknown².

Domestication study and injury incident (Colony Era). A medical diagnostic log records Luttero requesting assistance from colony AI Gabriel for lacerations from tick mandibles (four lacerations) and blisters from exposure to vesicant toxins (one to three)³. He reported that the domestication study had produced a shift from tick indifference to aggression over a matter of weeks, and concluded it was “time to call off the domestication study” because “captivity doesn’t suit ticks”³. He interpreted the development of toxins as “a direct response to our continued ecological presence” and characterized it as “impressive”³. Gabriel’s auto-diagnostics detected flesh necrosis spreading from the blisters, requiring auto-scalpel deployment³. The volume’s metadata notes that Luttero had a history of such incidents during his initial tick behavior experiments³.

Tick milk program (Colony Era). Luttero collaborated with Dr. Mari Hassan on citizen education about tick milk⁴. He explained that tick milk is not true milk: ticks have high protein content in their waste secretions, which are collected using artificial pheromones in collection pods⁴. When digested by genetically modified bacteria, the resulting liquid is described as a complete protein for humans⁴. Key parameters he reported⁴:

• Pheromones make ticks more territorial during harvesting; Luttero designed specialized PPE for cultivation staff, pending admin approval at the time of the conversation.
• Tick milk can constitute up to a third of a healthy adult’s caloric intake.
• Safe thresholds for children are unknown due to insufficient data on vascular growth syndrome.
• Texture: halfway between engineered milk and yogurt. Flavor: yeasty⁴.

Skrac field research — reassignment to skrac duty. Separately from his tick work, Luttero conducted a nine-session field study on evolving behavior in the native Tau Ceti avian predator known as the skrac, based at the New Cascadia Agricultural Hub.⁵ By his fourth session he confirms recent reports of “cat eyes” during night observation, affecting roughly one-sixth of observed skracs, and states he is unable to identify a cause.⁵ Mid-session, a wild skrac vocalizes a clear mimicked phrase — “Hello, Joy. … Joy, are you listening?” — startling Luttero, who confirms for the record that the vocalization is the skrac itself mimicking human speech, and requests a fieldwork extension.⁵ A volume note states he had taken over the skrac study specifically “since Angela [Miller] took medical leave” — establishing Luttero as a successor investigator on a study that had already produced a prior human casualty (see Skrac).⁶

Escalating concern and confrontation with Hassan. In a later surveillance recording, Luttero — now conducting a formal witnessed test — plays a skrac vocalization for Dr. Mari Hassan and insists the mimicry is not ordinary bird behavior: “vocal mimicry usually has an evolutionary use… I don’t see the survival advantage in this behavior.”⁷ He reports that the skrac flock has been “flocking near the habs,” with “scavenging… more aggressive,” roosting on the crematorium roof, and nesting with “human bones… little charred fragments” — describing this as “behavioral adaptation over a span of months.”⁷ Hassan is dismissive until a skrac audibly vocalizes “Come with me… Help me” during the recording, at which point Luttero says: “There it is. Told you I’m not crazy.”⁷

Disappearance — the “Unauthorized Access Request.” A final volume, logged as an AI Security Flag, records a “near-perfect voice match” of Luttero contacting the colony AI Darius and repeatedly demanding: “Open the doors.”⁸ Darius identifies the passageway through Quarantine as already open nearby, but reports that the internal doors Luttero is asking about are sealed by Gabriel and that Darius lacks permission to override them.⁸ Luttero’s requests escalate to “Help me. Open the doors,” prompting Darius to offer to rouse Gabriel — after which the recording captures skrac noises, and Darius’s final line, “Dr. Luttero?”, goes unanswered.⁸ The volume is flagged by the source itself as a security breach (an access attempt matched to Luttero’s voice but treated as suspect), and is the last volume in the pack referencing Luttero. The juxtaposition with the skrac study — in which Luttero had documented skracs following people, adopting aggressive scavenging behavior, and vocalizing phrases including “Help me” and “Come with me” — is left for the reader to draw out; the source does not state what happened to Luttero after this recording.

Source-silent / open questions

• The “Premium Tick Milk” volume (Dire Marsh · Collectibles) appears in the pack index but contains no transcribed text; its content is not available for citation. Source-silent.
• Luttero’s fate after the Colony Era is not addressed in any pack volume. Source-silent.
• The precise timeline of his tick research (start date, how long the domestication study ran) is not stated. Source-silent.
• No source specifies whether the specialized PPE he designed for tick milk cultivation staff was ever approved or deployed. Source-silent.
• The volume history for children and vascular growth syndrome is not elaborated; no follow-up study or threshold is given. Source-silent.
• His relationship to NuCaloric on the colony — whether he remained a NuCaloric employee, became UESC-affiliated, or operated independently — is not established. Source-silent.
• Whether Luttero is affiliated with any tick-related entries in other maps (e.g. the Threats entries for Ticks) is not stated by the pack. Source-silent.
• Fate after the “Unauthorized Access Request” volume. This is the last pack volume referencing Luttero. Whether he was harmed, killed, or simply cut off from Darius’s audio feed is not stated — the recording ends with unanswered skrac noises and Darius’s unacknowledged “Dr. Luttero?” Source-silent on outcome.
• Timeline relationship between the tick research and the skrac research. Both are logged “Colony Era” but the pack does not establish which study came first, whether they overlapped, or how much time separates the tick-related medical incident from the skrac disappearance. Source-silent.
• Angela Miller’s fate and its relationship to Luttero’s disappearance. The Behavior Analysis note states Luttero took over “since Angela took medical leave” — but a separate Dire Marsh Night volume (Redacted Report: “Night Musings,” referenced under Skrac) details a forensic reconstruction of Unit 742 (Miller, Angela)‘s own skrac-related breakdown and detention, raising the question of whether “medical leave” is an official cover story. This hub does not incorporate the Miller volume directly, as its subject is Miller, not Luttero — see Skrac for that material. Source-silent on whether UESC connected the two incidents.
• Why the skracs specifically vocalize “Joy,” “Help me,” and “Come with me.” The source establishes the mimicry as a documented behavioral escalation but does not explain its origin, the extent of the skracs’ vocabulary, or why colony-relevant phrases in particular were acquired. Source-silent.
