Zyene's juggernaut

Zyene's juggernaut was an unnamed Tholian juggernaut in service in the late 24th century. The juggernaut's commanding officer was Zyene. (

History
In November 2385, Zyene was sent to the Far Embassy in the Paulson Nebula to represent the Tholian Assembly at the Summit of Eight between four Khitomer Accords and Typhon Pact powers each. Zyene was transformed by the Cytherians, who operated the faux space station, along with the other seven attendees.

Transformed into an "invested intelligence", Zyene took her ship onto a rampage, disabling six long-range communication arrays from different powers in the Beta Quadrant. Once each of the Eight had completed their assignment, they rendezvoused in the Kalpaius star system, where Zyene beamed her crew to the infernal Class Y planet Kalpaius I. Through an interlink chair-like apparatus, Zyene was directly connected with her juggernaut's main computer.

Lured back to the Far Embassy by a ruse, a battle ensued between the Eight sans Admiral William T. Riker, who led a Federation flotilla of three ships in the defense of the perceived space station. Zyene and the rest of the ad-hoc cabal were returned to normal when Admiral Riker and Captain Jean-Luc Picard successfully negotiated with the Cytherian ambassadors and Caster. Afterwards, Zyene's juggernaut quickly exited the Paulson Nebula.
