Minn Warframe Guide — Tagfer, the Cavia and Netracells

Most people searching "minn warframe" come from the Whispers in the Walls storyline: Tagfer keeps talking about his partner Minn — who is she and what happened? This guide covers the full Minn/Tagfer background, the Cavia syndicate, and the weekly Netracells missions in one place (the official Wiki redirects "Minn" to Tagfer's page — they're one story entity).

Who Is Minn? (The Cervulite)

Minn is Tagfer's partner, a Cervulite (deer-like species) — one of the animals granted sentience in "Papa" Albrecht Entrati's Void experiments. Key facts:

  • Minn is missing or dead — the engine behind everything Tagfer does
  • Tagfer is obsessed with finding Albrecht, aiming to avenge Minn
  • The name: they were "tagged for disposal" — Albrecht meant to sacrifice the last two Cervulites to The Indifference (the Man in the Wall) to sate its hunger for uniqueness; after Minn's death, Tagfer named himself after that tag (tag → Tagfer)
The name easter egg

A Höllvania zoo exhibit shows an ancient horned ungulate — possibly a Cervulite ancestor — with its species name written in 1999-era proto-Orokin script as TGFR ("Tagfer").

Tagfer: Cavia Member and Netracells Unlocker

Tagfer (voiced by Sean Slater) is a member of the Cavia syndicate — the animals granted sentience by Void experiments in the Sanctum Anatomica:

  • Cavia members: Kalymos, Tagfer, Fibonacci, Bird 3
  • Tagfer's grudge against Albrecht over Minn's death runs through Whispers in the Walls and the updates after it
  • Practical value: Tagfer unlocks the weekly Netracells missions — a hard weekly with fat rewards (Arcanes, relics, standing) and a must-run piece of the late-game week
Don't skip weekly Netracells

Pick them up from Tagfer; one run pays multiple reward types (Arcanes and relics included). Alongside the Descendia weekly and the Steel Path Circuit, they're one of the big three weekly chores in 2026 — the other two are covered in the Ignia guide and the Prime warframes guide.

The Cavia Syndicate and Standing

Cavia runs out of Sanctum Anatomica (deep in the Deimos Cambion Drift):

  • Rank up for: the Arcane store (Vosfor system), cosmetics, mission access
  • Vosfor (the Arcane-dissolve currency) is exchanged through Loid (Cavia) — the full economy chain is in the Riven market guide
  • Cavia Rank 5 is a prerequisite in Roathe's storyline (the Honoria syandana)

Whispers in the Walls (Background Questline)

Whispers in the Walls (Update 35, December 2023) is the gateway quest into the Tau content line:

  • Albrecht's laboratory, the Void breach
  • Cross-Save launched in the same update (see the cross-platform guide)
  • Introduced Arcane dissolving (Vosfor) and the Cavia syndicate
  • Where the story goes next: The Lotus Eaters → The Old Peace (Tau storyline, Valdur debuts) — full plot in the Valdur & Tau storyline guide

Story Reads and Common Questions

  • Minn's status: the official Wiki describes her as "missing or dead" — the truth is still unfolding, and the 2026 version line hasn't delivered a final verdict
  • Tagfer's vengeance: he's not a "villain" — his motive is grief; his interaction with the Operator continues through later updates (including the KIM system)
  • The species: Cervulites are deer Void-modified into sentience — every Cavia member shares that origin
