Sabotage in Ta-Metru and Ga-Metru#

The campaign opened with two coordinated attempts on the lives of the Toa as they entered the field. OnewaOnewaOnewa served as Toa Metru of Stone, led Po-Koro through the Dark Time, and constructed the Metru Nui statue honoring the fallen Toa Mahri Matoro. and VakamaVakamaA Ta-Metru maskmaker transformed into the Toa Metru of Fire, leader of his team through the Visorak war, and Turaga of Ta-Koro for a thousand years. entered Ta-MetruTa-MetruThe fire district where Ta-Matoran perfected their craft and powered Metru Nui's industry for thousands of years. by transit chute. The chute was diverted in mid-passage onto a trajectory that emptied directly into the molten contents of the ProtodermisThe Great Spirit Robot, explainedBionicle's whole universe lives inside a 40-million-foot robot built by the Great Beings.

Nidhiki, a Dark HunterTeridaxTeridax orchestrated a thousand-year scheme that ended with him occupying the Great Spirit Robot itself before his death on Bara Magna. operating in the city under contract from forces neither Toa yet understood, had set the trap. VakamaVakamaA Ta-Metru maskmaker transformed into the Toa Metru of Fire, leader of his team through the Visorak war, and Turaga of Ta-Koro for a thousand years. opened his palms to the heat coming up at them and absorbed the flames into himself. He released the accumulated heat in a single directed beam, which struck the roof of the Reclamation Center and blew an exit through it. Both Toa cleared the structure before the chute deposited them in the protodermis.

It was VhisolaVhisolaVhisola was a Ga-Matoran student of Nokama, one of the six finders of a Great Disk, whose research deduced the location of the Morbuzakh King Root. who provided the operational breakthrough. Her own pre-Toa research into the MorbuzakhMorbuzakhA sentient plant monster created by Teridax to terrorize Metru Nui and control its population through fear. had identified that the plant possessed a sentient central core, and that the surface vines were merely extensions of that core's reach. The plant could not be killed by attacking the vines. It had to be killed at its root. The root would be sited in the hottest place in the city, since the plant fed on heat.

The team had now spent the bulk of their reserves on the corridor and the entry vine. They retreated tactically, baiting the King RootThe King RootThe sentient central core of the Morbuzakh plant, grown in the Great Furnace of Ta-Metru and destroyed by the Toa Metru using the fused Great Disks. into extending itself further into the chamber to pursue them.

The unanswered question#

The campaign had been won, but the question NokamaNokamaNokama served as Toa Metru of Water, endured the Hordika mutation, and led Ga-Koro and later Ga-Metru as Turaga through three eras. raised in the immediate aftermath went unanswered. The MorbuzakhMorbuzakhA sentient plant monster created by Teridax to terrorize Metru Nui and control its population through fear. had been commanded by another. That commander remained at large, and would now know that the Toa MetruToa Metru and Toa HordikaSix Matoran elevated by Lhikan to save their city, mutated by Visorak venom, and restored in time to deliver the population to safety. had assembled the Great DisksThe Great DisksThe six legendary Kanoka of Metru Nui, one hidden in each district, recovered by the Toa Metru during the Morbuzakh crisis and later fused into the Kanohi Vahi. and were preparing to present them to Turaga DumeTuraga DumeThe Turaga of Metru Nui for sixteen thousand years, a former Toa of Fire who saved Lhikan's life and was abducted and impersonated by Teridax. at the ColiseumThe ColiseumCentral tower of Metru Nui, serving as government seat, sporting arena, and, during Teridax's masquerade, a prison for the city's Matoran population. as evidence of their legitimacy. The presentation never occurred in the form the team intended.
