Arjun Dasari
Colony scientist assigned to Dr. Valentin Cole’s Anomaly Investigative Team — subject of the time-dilation incident (Report #45), repeated exposure events, and the final disappearance documented in Anomaly Incident Report #56.
What the source establishes — canon
Co-author on the subterranean radiation theory. A paper recovered from the New Cascadia research database, authored by V. Cole, A. Dasari, and M. Stafford, proposes that the Anomaly originates below the planet’s surface — “a form of terrestrial radiation caused by natural substances present on Tau Ceti IV” — and notes that attempts to study this radioactive decay were “repeatedly impeded by AI malfunction,” forcing the team to work manually1.
The time-dilation incident (Incident Report #45). During routine biosample collection, Dasari entered the vicinity of the Anomaly. Cole, serving as on-duty supervisor, observed Dasari to be absent for 10 minutes. Dasari, however, claimed to have been gone at least 3 hours. The report also references hallucinations and “lost time,” with a fragment indicating Dasari was “inexplicably drawn” — the surrounding context is lost to data corruption2.
Second exposure event (Incident Report #51). On a perimeter walk of the Anomaly site, Dasari encountered an event described only in fragments: confusion and misunderstanding resulting in an argument. Dasari claimed to hear “singing inaudible to the human ear” and saw “aggressive creatures of memory.” He was admitted to Medical for assessment and ultimately cleared2.
Psychological deterioration and medical leave (Incident Report #55). A later report — its number and most of its content lost to corruption — documents severe psychological disturbances resulting in mandatory medical leave for an unnamed subject. The surrounding fragments indicate this individual continued to return to the Anomaly site despite restriction and supervision. Given the sequential context (Reports #45, #51 both concern Dasari, Report #56 documents his disappearance), the subject of Report #55 is identified within the document series as Dasari — though the corrupted text does not name him explicitly2.
Disappearance (Incident Report #56). The final incident report in the series records that Dasari disappeared from medical holding and did not return. The file ends: “without a trace” before corruption terminates the record2.
Confirmed dead — body recovered by Cole. In a separate, heavily corrupted audio report, Cole returns to the Anomaly site and states: “No sign of Dasari… but temporal abnormalities persist.” Later in the same recording Cole remarks: “The suit has Dasari’s number. This body’s been here for years. Well past advanced stages of decay.” The precise timeline of discovery relative to the disappearance is not recoverable from the corrupted record3.

Source-silent / open questions
- Dasari’s professional role and title are not stated in any source. He is identified by surname only in the incident reports, and as “A. Dasari” in the paper citation. No affiliation, rank, or specialisation is given beyond membership in Cole’s investigative team.
- The specific nature of the “argument” during the perimeter walk (Incident Report #51) is lost to corruption. The identity of the party Dasari argued with is unknown.
- The subject of Incident Report #55 is inferred to be Dasari from sequential context; the corrupted text does not name him. Source-silent on whether this inference is correct.
- Whether Dasari died inside the Anomaly or elsewhere before Cole’s discovery is not established. Cole’s recording does not fix a date, and the dating metadata is listed as incomprehensible.
- Dasari’s relationship to Cole before the expedition (colleagues, strangers, etc.) is not stated. His relationship to Stafford (the third co-author) is likewise source-silent.
- No source in the pack gives Dasari’s first name in full. The initial “A.” in the paper citation is the only identification. The full name “Arjun Dasari” does not appear verbatim in the source — source-silent on the first name.
