Grineer Queens

"Hush, Worm. Let the beasts do their work."

- Elder Queen

The Grineer Queens, also called the Twin Queens, are the rulers of the Grineer Empire. All Grineer are genetically engineered at "birth" to display and feel absolute loyalty to the Queens.

Lore
The Queens are shrouded in mystery. Even the Lotus has precious little information about them, once believing them to be only myths propagated by the Grineer. The only historian to claim any knowledge of the Queens' origins is the sculptor of the Kuria statues, Olemedi. According to the poem encrypted within the Kuria statues, the Queens were daughters of an Orokin aristocrat who were shunned by the Orokin due to the stigma surrounding the birth of twins. During the fall of the Orokin Empire, the Queens were somehow able to command the respect of the Grineer slaves, becoming their leader.

Vor's Prize
Shortly before the awakening of the player's first Warframe, the Queens demanded an audience over long-range communicator with Admiral Vor. As a result of his repeat failures, the Queens demote Vor to Captain, promoting Boril in his place, and ordering Vor to kill any Warframes he comes across.

Operation: Eyes of Blight
Despite the destruction of several Relays by the Fomorian fleet, the Queens express great dissatisfaction with the progress made by Councilor Vay Hek, citing an increase of Tenno attacks on Grineer operations and the massive drain of resources needed to replace the destroyed Fomorians. They also threaten to replace the Councilor with burgeoning scientist Tyl Regor.

The War Within
The Queens are finally revealed when the Tenno tracks down Teshin to the Kuva Fortress, a mobile asteroid base that has remained hidden from detection. The Queens had ordered Teshin, a Dax soldier whom they command loyalty of, to deliver a Tenno Operator to them, and are able to use a device on the Tenno's Warframe to sever their Transference link in an attempt to subsume their consciousness. It is revealed that the Queens plan to enact an Orokin ritual known as the Continuity, that would allow them to transfer their consciousness to a new body, essentially granting them immortality. With Teshin's help, the Tenno are able to break out of the Queen's device, and in the ensuing skirmish manage to destroy the Queen's guard.

Depending on the choices the player makes during the quest, the Elder Queen can be killed either by Teshin or the Tenno, or left alive.
