Launch an assault on Grineer burial grounds and send a message to Vay Hek.
This is one of the four possible bounties that can show up on Konzu's bounty board in Cetus during Operation: Ghoul Purge. This bounty has the Tenno clear a large number of smaller burial grounds, and always ends with the stage "Ghoul Hunt". Below are the unique dialogue lines that are heard when beginning and ending the bounty, and when running the different stages. The "Cache Recovery" and "Rescue" stages do not seem to appear in this bounty. All seven possible stages are listed below, but each bounty will have a maximum of four stages.
Konzu: "We got a ghoul regiment about to take the Plains. Scans show a mass of biosignatures ready to break ground. Find them and smash them. I need my Plains safe again."
Lotus: "Vay Hek believes the ghouls are his ultimate weapon, that they are undefeatable. Shatter his confidence by wiping out his prize soldiers in battle."
Lotus: "Bring me a live ghoul. I want to see what it can tell me about Vay Hek's intentions."
(upon arriving at the waypoint) Lotus: "Something makes these ghouls different from other Grineer. I need to know what. Bring me one for study."
(upon completing the stage) Lotus: "Our captive appears non-verbal but that does not mean he has no secrets to share. I'll update you on my progress."
Lotus: "Ghoul alphas are the strongest of the strong, leaders of the pack, Vay Hek's pride and joy. Send a message to Vay Hek by killing this pack's alpha."
(upon arriving at the waypoint) Lotus: "Every pack has an alpha. I've identified one. Draw out this ghoul and destroy it."
(upon completing the stage) Lotus: "All that anger and no leader left to channel it. Vay Hek will not be pleased."
Lotus: "Vay Hek has planted too many ghouls to take out in open combat. We need to poison them before they can break ground. Get to my waypoint."
(upon completing the stage) Lotus: "The grokdrul poison is doing its work. You have sent a clear message to Vay Hek."
Lotus: "Give these ghouls no advantage. Break into nearby armoured vaults and take everything inside."
(upon arriving at the waypoint) Lotus: "Ghouls come out of the ground hungry for supplies. Break into these vaults and leave them with nothing."
(upon completing the stage) Lotus: "Well done. We need every advantage we can get against these ghouls."
Lotus: "Vay Hek plans to enhance his ghouls with a hormone infusion. Intercept the infusers and destroy them."
(upon arriving at the waypoint) Lotus: "The Grineer are dropping in growth hormone infusers to speed up ghoul gestation. I've located some of these infusers. Destroy them."
(upon completing the stage) Lotus: "Well done. Stronger ghouls are the last thing we need."
This is always the last stage of the bounty.
Lotus: "I need you to take out local concentrations of ghouls before we begin our final assault."(upon completing the bounty) Konzu: "Ai yo, those dirt-nappers didn't know what hit 'em. Few more runs like this and the Plains will be back to normal… levels of danger."
