In the ever-shifting landscape of 2026's Origin System, the hunt for the Sisters of Parvos remains one of the most exhilarating rites of passage for a Tenno. The promise of a loyal (or vengeful) Corpus Lich, armed with a devastatingly powerful weapon and a personality as sharp as a Razorback's claws, has drawn countless operatives into the shadowy depths of Corpus territory. What began as a 2021 update has matured into a refined endgame obsession, yet the core ritual still demands cunning, preparation, and a dash of luck.

For one veteran Tenno—let’s call her Kiara—the journey began aboard her Orbiter, staring at a holographic dossier. She had already braved the psychological trials of The War Within and sailed through the ghostly tempests of Call of the Tempestarii. These two quests were not mere suggestions; they were the iron gates barring entry to the Sisterhood. Without them, any attempt to summon a candidate would be met with empty Golden Hands and wasted Granum Crowns. Kiara double-checked her Codex, then nodded to her Cephalon. The first step was unquestionably complete.
✨ The Hunt for a Zenith Crown
The next piece of the puzzle was currency—not Credits or Platinum, but a Zenith Granum Crown. Kiara knew the drill: she had to track down a Corpus Treasurer on any mid-to-high level Corpus Ship mission, let him summon reinforcements, and then relieve him of his cargo. It was a frantic ballet of gunfire, but within minutes a glowing coin decorated her palm. One Zenith Crown, one ticket to the pocket dimension where Parvos Granum himself watched over his potential heirs.
She loaded into a standard Corpus Ship tileset aboard her Saryn Prime, the air thick with coolant mist and the hum of drop ships. The Golden Hand stood at an intersection, its surface pulsing with Void energy. With a swift movement, Kiara inserted the Zenith Crown. The world warped, and she was sucked into the Granum Void—a golden netherworld populated by shimmering Specter Particles and Errant Specters.
🔹 Dancing in the Void
Inside the Void, a timer blinked on her HUD. The rules were unspoken but well-known: she had to reach at least Rank 1 of the progression meter before the exit portal spawned, and more crucially, she had to personally eliminate no fewer than twenty-five enemies. Kiara moved like a plague-touched wraith, spores spreading from her fingertips as she carved through specters with her Kuva Nukor. The meter climbed—Rank 1 achieved. She kept her kill count in her peripheral vision: 27, 28, 29. At thirty-two, the portal yawned open, and she leaped through.
What awaited her on the other side was the true prize.
⚔️ The Candidate Rises
Stepping back onto the Corpus Ship, her Warframe’s sensors immediately flagged a new signature. There, striding through a corridor of crates and conveyor belts, was a towering female figure shrouded in Corpus attire, her face a mask of cold ambition. A blue marker hovered above her head, the unmistakable sign of a Sister candidate. Kiara wasted no time. Saryn’s Miasma engulfed the area, stripping shields and then flesh, until the candidate collapsed in a heap of sparks and fading tech.
A holographic post-kill screen materialized, displaying the weapon that this Sister would have carried throughout her reign. The Kuva Zarr, the Tenet Arca Plasmor, the Tenet Diplos—the rotation was entirely random. Kiara noted the model: a Tenet Envoy with a 53% Heat bonus. Not bad, but not the Toxin progenitor she had hoped for. Here lay the dilemma: she could either claim this candidate, binding the Sister to that specific weapon and elemental bonus forever, or reject the offer and run the entire sequence again, from Crown to Crown, hoping for a different roll. The choice was hers.
🔧 The Progenitor’s Touch
What many fledgling Tenno overlook is the role of the Warframe used to strike the killing blow. The frame acts as a progenitor, imprinting a permanent damage bonus on both the Sister and her eventual weapon. Kiara had chosen Saryn for the encounter, which would infuse the Sister with Toxin. Had she used Gauss, she would have gotten Heat; a Mag would have granted Magnetic. The table of elements was vast:
| Progenitor Warframe Example | Damage Type Imprinted |
|---|---|
| Saryn, Nidus, Grendel | Toxin |
| Frost, Gara, Revenant | Cold |
| Volt, Gyre | Electricity |
| Mag, Xaku | Magnetic |
| Ember, Nezha, Protea | Heat |
| Harrow, Khora, Atlas | Impact |
| Loki, Ivara, Ash | Puncture |
| Excalibur, Baruuk, Wisp | Slash |
Knowing this, Kiara hesitated for only a heartbeat. She accepted the candidate. The fallen figure dissolved into a burst of radiation, a new Sister born into the Origin System. A territorial claim instantly appeared on her Star Chart—a node on Venus now bled Corpus red. From this moment forward, the Sister would send out taunting holo-messages, siphon her mission rewards, and steadily grow more powerful unless stopped.
🌟 The Road Ahead
Getting the Corpus Lich is merely the prologue. Once a Tenno has their Sister, they must begin the real hunt: collecting Requiem Relics, deciphering the sequence of three Requiem Mods, and finally confronting the Sister in a Railjack showdown above Neptune’s clouds. Kiara checked her Parazon and smiled grimly. She had a long road of Requiem murmur farming ahead, but at least now she had a nemesis worthy of the chase. The cycle would repeat—fail, decipher, attempt—until the Sister knelt before her and offered either a converted ally or a vanquished weapon.
For any Tenno looking to replicate Kiara’s path, the steps remain engraved in the void: complete the essential quests, secure a Zenith Granum Crown, reach Rank 1 and slay at least 25 specters in the Granum Void, then down the marked candidate and make your weapon choice. The Corpus Lich system has only grown more rewarding with time, and in 2026, a new wave of Sisters continues to test the mettle of even the most seasoned warriors. Whether you seek mastery, fashion, or sheer destructive power, a Sister of Parvos awaits your challenge.
