Origin and the Brotherhood tribute#

The Blade Burrowers were not a wild species. They were a product of the Brotherhood of MakutaThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit.'s long-running role as the suppliers of RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts. to the wider Matoran UniverseMatoran UniverseA civilization of biomechanical beings living inside a colossal robot, destroyed when Teridax seized control., and specifically of the arrangement the Brotherhood had been pressed into by the BarrakiThe BarrakiSix warlords who built an empire spanning most of the Matoran Universe, fell in a single Brotherhood ambush, and spent millennia mutated in the Pit.. When the warlords of the League of Six KingdomsLeague of Six KingdomsThe League of Six Kingdoms was an alliance composed of various species, with ties to Xia and many other islands. Connected to both the Order of Mata Nui and the Brotherhood of Makuta, the League included Pridak among its ranks, and its members collectively held several powers of unknown scope. Its stated objective was the overthrow of Mata Nui. had divided the universe into territories and demanded that the MakutaMakuta (Species)Shadowy Antidermis beings and the Brotherhood's elite, Makuta commanded darkness and shaped the Matoran Universe's fate. continue to provide them with RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts. and other engineered beasts, the obligation fell heavily on those MakutaMakuta (Species)Shadowy Antidermis beings and the Brotherhood's elite, Makuta commanded darkness and shaped the Matoran Universe's fate. whose specialty was the manufacture of new life forms. MutranThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit. was the most prolific of that group, and a significant portion of his catalogue passed through Brotherhood channels into the hands of BarrakiThe BarrakiSix warlords who built an empire spanning most of the Matoran Universe, fell in a single Brotherhood ambush, and spent millennia mutated in the Pit. commanders. The Blade Burrowers were one such product, designed and delivered for the personal use of KalmahKalmahA red-and-black Barraki warlord of the League of Six Kingdoms, imprisoned in the Pit and mutated into permanent aquatic form..

The arrangement was not affectionate on either side. KalmahKalmahA red-and-black Barraki warlord of the League of Six Kingdoms, imprisoned in the Pit and mutated into permanent aquatic form. had never shown the deference that a MakutaThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit. considered his due, and MutranThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit. responded by ensuring that every RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts. consignment sent to KalmahKalmahA red-and-black Barraki warlord of the League of Six Kingdoms, imprisoned in the Pit and mutated into permanent aquatic form.'s armies was deliberately short-lived. The Blade Burrowers were built with a designed expiration date of no more than several days. The intention was that the creatures would serve their assigned role for KalmahKalmahA red-and-black Barraki warlord of the League of Six Kingdoms, imprisoned in the Pit and mutated into permanent aquatic form.'s next engagement and then collapse without further support from their maker. The arrangement also gave MutranThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit. a quiet measure of revenge for what he regarded as repeated insults from a warlord who had no proper appreciation of MakutaThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit. craftsmanship.

The Blade Burrowers were sent.

The species was used as field tunnellers, ambushers, and burrowing siege auxiliaries during KalmahKalmahA red-and-black Barraki warlord of the League of Six Kingdoms, imprisoned in the Pit and mutated into permanent aquatic form.'s reign.

Form and abilities#

A Blade BurrowerBlade Burrower: The Tunnelling Rahi of Metru NuiBlade Burrowers were powerful, near-blind Rahi that dug endless tunnels in a fixed pattern, a behavior the Great Beings engineered into them and that no one who studied the creatures was ever able to fully explain. was a low-set, heavily built RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts. constructed for sustained digging. Its forelimbs ended in powerful claws shaped for cutting through stone, packed earth, and the structural protodermis layers of the underground. The species hunted not by sight but by scent. Its eyesight was poor enough that visual recognition of prey at distance was unreliable, and the recorded behavioural pattern was one of scent-tracking through tunnel networks toward a moving target. The compensation was thorough: a Blade BurrowerBlade Burrower: The Tunnelling Rahi of Metru NuiBlade Burrowers were powerful, near-blind Rahi that dug endless tunnels in a fixed pattern, a behavior the Great Beings engineered into them and that no one who studied the creatures was ever able to fully explain. in a tunnel of its own making could orient on a quarry the VahkiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts. could not follow.

The species' most distinctive physical feature was its long, club-shaped tail. When a Burrower surfaced and was threatened or cornered, it swung the tail in wide horizontal arcs, knocking aside attackers and pushing surrounding creatures into panic flight. The combination of the tail and the species' size made a single agitated Burrower a serious hazard to anything in the immediate area. VahkiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts. protocol on Metru NuiMetru NuiThe city beneath Mata Nui functions as the Great Spirit's brain, housing the Matoran whose labor keeps the god alive. called for rapid containment of any surfaced Burrower into a holding container, on the understanding that the secondary damage from the swung tail would otherwise compound the original disturbance.

The defining behaviour was the digging. Individually, a Blade Burrower tunnelled at need, foraging and pursuing prey through whatever subsurface the local terrain offered. When the species gathered in sufficient numbers, the behaviour changed. The compulsion became geometric. The Burrowers no longer tunnelled at random but began carving a repeating pattern across the volume of stone available to them, working continually and without apparent purpose. Two long curved tunnels ran roughly north and south, with smaller subsidiary tunnels arranged between them, and the same configuration was repeated through every accessible region.

The compulsion was first identified after the fall of the League of Six KingdomsLeague of Six KingdomsThe League of Six Kingdoms was an alliance composed of various species, with ties to Xia and many other islands. Connected to both the Order of Mata Nui and the Brotherhood of Makuta, the League included Pridak among its ranks, and its members collectively held several powers of unknown scope. Its stated objective was the overthrow of Mata Nui., when the BrotherhoodThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit.'s strike on the BarrakiThe BarrakiSix warlords who built an empire spanning most of the Matoran Universe, fell in a single Brotherhood ambush, and spent millennia mutated in the Pit. command structure had collapsed KalmahKalmahA red-and-black Barraki warlord of the League of Six Kingdoms, imprisoned in the Pit and mutated into permanent aquatic form.'s holdings and the surviving lieutenants had abandoned the fortress.

The location was, by MutranThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit.'s own assessment, unpleasant: the northwestern reaches of the League's former territory smelled of rotting RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts., and a substantial fraction of that scent traced to MutranThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit.'s own short-lived deliveries from earlier campaigns. The fortress had been sacked by KalmahKalmahA red-and-black Barraki warlord of the League of Six Kingdoms, imprisoned in the Pit and mutated into permanent aquatic form.'s own remnant army before BrotherhoodThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit. forces arrived. Nothing of strategic value was left intact.

MutranThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit. cleared a space in the rubble to sit and noticed a carving on a remaining piece of stone. The carving was a record of what KalmahKalmahA red-and-black Barraki warlord of the League of Six Kingdoms, imprisoned in the Pit and mutated into permanent aquatic form. had discovered about the Blade Burrowers in his service. A population of the creatures had outlived the expiration MutranThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit. had built into them, and KalmahKalmahA red-and-black Barraki warlord of the League of Six Kingdoms, imprisoned in the Pit and mutated into permanent aquatic form. had spent his last period of authority observing the network of tunnels they were producing beneath the fortress. The shape was not random. The tunnels formed a deliberate, repeating pattern, and KalmahKalmahA red-and-black Barraki warlord of the League of Six Kingdoms, imprisoned in the Pit and mutated into permanent aquatic form. had concluded that the Blade Burrowers were carving a map. He had not deciphered what the map represented before the war ended.

MutranThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit. inherited the question. He could not match the carved geometry to any landmass on any chart available to the BrotherhoodThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit.. He later went to the length of capturing a Toa wearing a Kanohi RauKanohi RauThe Kanohi Rau allowed its wearer to comprehend foreign written and spoken languages, and was most associated with Turaga Nokama., the Mask of Translation, and forcing the prisoner to address the Burrowers directly. The communication failed. The Burrowers had no understanding of the pattern themselves, only the compulsion to keep cutting it. The map was real, the geometry was deliberate, and the species' purpose in producing it remained, by MutranThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit.'s own admission, a mystery that haunted him long afterward.

The pattern was later identified independently of MutranThe Brotherhood of MakutaAn organization of Makuta created by Mata Nui to police his universe and build Rahi, later seized by Teridax and turned into the instrument of the Plan that overthrew the Great Spirit.'s investigation. The shape the Blade Burrowers cut into stone was the symbol of the Three VirtuesThe Three VirtuesThe Three Virtues were the foundational principles given by Mata Nui to the Matoran, shaping social order, ritual, and the cosmology of Spherus Magna., the device representing Unity, Duty, and Destiny that recurred throughout MatoranMatoran UniverseA civilization of biomechanical beings living inside a colossal robot, destroyed when Teridax seized control. culture and across the Great Spirit Mata NuiMata NuiBuilt by the Great Beings to restore Spherus Magna, Mata Nui sustained an entire civilisation inside his body, was deposed by Teridax, and reclaimed his purpose as a mortal on Bara Magna.'s body. The reading was that the design had been embedded into the species by their engineers, intentionally or otherwise, and that the unconscious tunnelling was a memorial inscription meant to remind the Great SpiritMata NuiBuilt by the Great Beings to restore Spherus Magna, Mata Nui sustained an entire civilisation inside his body, was deposed by Teridax, and reclaimed his purpose as a mortal on Bara Magna. of his mission.

The reading reframed the Blade Burrowers from a wartime tunnelling asset into a piece of distributed ritual architecture, a continuous biological inscription of the Three VirtuesThe Three VirtuesThe Three Virtues were the foundational principles given by Mata Nui to the Matoran, shaping social order, ritual, and the cosmology of Spherus Magna. beneath whatever surface the species took root in.
