The Cavern of the Elements
Where the Great Beings Forged the Element Lords
A chamber within the Great Beings' underground lab at Tajun, the Cavern of the Elements was the room in which seven Glatorian and a leader-class Skrall were transformed into the seven Element Lords of Spherus Magna.

The purpose for which the cavern was used#
The Great BeingsThe Great BeingsScholar-inventors of Spherus Magna whose creations shaped the Matoran Universe and whose absence defined the conflicts that followed. had reached a point at which they wished to withdraw from the daily tedium of administration and governing. They were, by their own self-understanding, creators first and rulers second, and the time required to manage the planet's six tribes and its separate leader-class SkrallThe Skrall Conquest of Bara MagnaThe year of consolidation in which Tuma turned the Roxtus garrison into a continental military power, struck a covert alliance with the Bone Hunters, and set the southern villages on the road to the Battle of Roxtus. population was time they could not give to their wider projects. The solution they devised was to install delegated rulers who could govern the tribes in their stead.
The selection process produced one candidate from each tribe. Six were members of the GlatorianGlatorianTribal warriors of Spherus Magna who settled disputes through arena combat, until the Skrall conquest enslaved most of them. species, drawn one each from the Fire, Water, Ice, Jungle, Sand, and Earth tribes of Spherus MagnaSpherus MagnaA desert world of ancient conflict that became the merger point of the Matoran Universe and Bionicle's true endpoint., and the seventh was a leader-class SkrallThe Skrall Conquest of Bara MagnaThe year of consolidation in which Tuma turned the Roxtus garrison into a continental military power, struck a covert alliance with the Bone Hunters, and set the southern villages on the road to the Battle of Roxtus. representing the Rock TribeThe Skrall Conquest of Bara MagnaThe year of consolidation in which Tuma turned the Roxtus garrison into a continental military power, struck a covert alliance with the Bone Hunters, and set the southern villages on the road to the Battle of Roxtus.. No candidate was drawn from the Iron Tribe, which had fallen apart after the Dreaming Plague had almost wiped its population out, and no Element LordElement Lord of RockFormer leader-class Skrall remade by the Great Beings into a being of living stone, ruler of the Rock Tribe during the Core War, and the elemental claimant who turned the river fight in the Valley of the Maze. of Iron was ever created. The selected warriors were brought to the Cavern of the ElementsElementsThe full elemental system of the Matoran Universe, covering the six primary elements, the secondary group, the opposed pair of Light and Shadow, and the apex Element Lord tier of Spherus Magna. and presented to the Great BeingsThe Great BeingsScholar-inventors of Spherus Magna whose creations shaped the Matoran Universe and whose absence defined the conflicts that followed. for transformation.
The transformation procedure#
Within the cavern, the Great BeingsThe Great BeingsScholar-inventors of Spherus Magna whose creations shaped the Matoran Universe and whose absence defined the conflicts that followed. successfully altered the seven prospective Element LordsElement Lord of RockFormer leader-class Skrall remade by the Great Beings into a being of living stone, ruler of the Rock Tribe during the Core War, and the elemental claimant who turned the river fight in the Valley of the Maze., giving each great power and control over their individual element. The procedure was uniform across all seven candidates in its general form, although the elemental output it produced was specific to each subject. The GlatorianGlatorianTribal warriors of Spherus Magna who settled disputes through arena combat, until the Skrall conquest enslaved most of them. from the Fire TribeFire TribeThe master smiths of Bara Magna who forged tools for all tribes before the Shattering scattered them into conflict. emerged as the Element Lord of FireElement Lord of FireFormer Glatorian of the Fire Tribe, remade by the Great Beings into an immortal being of pure flame, ruler of the Fire Tribe through the Core War, and the elemental claimant whose feud with the Element Lord of Ice broke open again in the White Quartz Mountains., with the ability to create and control fire. The candidate from the Ice TribeIce TribeOne of Bara Magna's six major tribes, the Ice Tribe produced legendary Glatorian like Strakk and survived the Shattering intact. emerged as the Element Lord of IceElement Lord of IceThe Element Lord of Ice is a member of the Element Lords and a former Glatorian who once served as the leader of the Ice Tribe on Spherus Magna. Wielding the element of ice and bearing white coloration, the Element Lord of Ice resides on the reformed Spherus Magna, the homeland from which the species originated. with corresponding mastery of his element. The leader-class SkrallThe Skrall Conquest of Bara MagnaThe year of consolidation in which Tuma turned the Roxtus garrison into a continental military power, struck a covert alliance with the Bone Hunters, and set the southern villages on the road to the Battle of Roxtus. emerged as the Element Lord of RockElement Lord of RockFormer leader-class Skrall remade by the Great Beings into a being of living stone, ruler of the Rock Tribe during the Core War, and the elemental claimant who turned the river fight in the Valley of the Maze., made of rock and charged with leadership of the Rock TribeThe Skrall Conquest of Bara MagnaThe year of consolidation in which Tuma turned the Roxtus garrison into a continental military power, struck a covert alliance with the Bone Hunters, and set the southern villages on the road to the Battle of Roxtus.. The remaining four lords followed the same pattern in their respective elements of Water, Jungle, Sand, and Earth.
The transformation was thorough. Every part of each subject was affected by the procedure, and the resulting Element LordsElement Lord of RockFormer leader-class Skrall remade by the Great Beings into a being of living stone, ruler of the Rock Tribe during the Core War, and the elemental claimant who turned the river fight in the Valley of the Maze. bore little physical resemblance to the GlatorianGlatorianTribal warriors of Spherus Magna who settled disputes through arena combat, until the Skrall conquest enslaved most of them. or SkrallThe Skrall Conquest of Bara MagnaThe year of consolidation in which Tuma turned the Roxtus garrison into a continental military power, struck a covert alliance with the Bone Hunters, and set the southern villages on the road to the Battle of Roxtus. bodies in which they had walked into the cavern. They retained, however, their identities and their names. The continuity of person across the transformation was deliberate, and it was the basis on which the lords were able to assume political authority over their tribes immediately after the procedure. They were not new beings being introduced to populations that had no relationship with them. They were the same individuals, recognised by their former peers, now empowered to command those peers.

After the transformation was complete, the Great BeingsThe Great BeingsScholar-inventors of Spherus Magna whose creations shaped the Matoran Universe and whose absence defined the conflicts that followed. equipped the new Element LordsElement Lord of RockFormer leader-class Skrall remade by the Great Beings into a being of living stone, ruler of the Rock Tribe during the Core War, and the elemental claimant who turned the river fight in the Valley of the Maze. with armour and weapons fitted to their elements. The equipment was supplied as part of the same operation in which the transformation had been carried out, and it was suited to the elemental output the Element LordsElement Lord of RockFormer leader-class Skrall remade by the Great Beings into a being of living stone, ruler of the Rock Tribe during the Core War, and the elemental claimant who turned the river fight in the Valley of the Maze. now possessed. The lords were then placed in control of their corresponding tribes across Spherus MagnaSpherus MagnaA desert world of ancient conflict that became the merger point of the Matoran Universe and Bionicle's true endpoint., with each lord assigned the tribe from which his or her GlatorianGlatorianTribal warriors of Spherus Magna who settled disputes through arena combat, until the Skrall conquest enslaved most of them. or SkrallThe Skrall Conquest of Bara MagnaThe year of consolidation in which Tuma turned the Roxtus garrison into a continental military power, struck a covert alliance with the Bone Hunters, and set the southern villages on the road to the Battle of Roxtus. self had originated.

For thousands of years, the seven Element LordsElement Lord of RockFormer leader-class Skrall remade by the Great Beings into a being of living stone, ruler of the Rock Tribe during the Core War, and the elemental claimant who turned the river fight in the Valley of the Maze. ruled together in relative peace, and the Great BeingsThe Great BeingsScholar-inventors of Spherus Magna whose creations shaped the Matoran Universe and whose absence defined the conflicts that followed. were freed from the administrative load that had prompted the experiment in the first place.

Consequence and the long aftermath#
The peace lasted only as long as the elemental rulers had nothing of overriding value to dispute.

Frequently asked questions
- What was the Cavern of the Elements?
- The Cavern of the Elements was a chamber inside the underground laboratory of the Great Beings at Tajun on Spherus Magna. It was the room in which the seven Element Lords were brought into being through a single deliberate act of transformation.
- Why did the Great Beings create the Element Lords in the Cavern of the Elements?
- The Great Beings wished to withdraw from the daily tedium of administration and governing, regarding themselves as creators first and rulers second. They devised the solution of installing delegated rulers who could govern the tribes in their stead, freeing them for their wider projects.
- Who was transformed in the Cavern of the Elements?
- Seven warriors were transformed, one from each group. Six were members of the Glatorian species drawn from the Fire, Water, Ice, Jungle, Sand, and Earth tribes, and the seventh was a leader-class Skrall representing the Rock Tribe. No candidate was drawn from the Iron Tribe, which had fallen apart after the Dreaming Plague, so no Element Lord of Iron was ever created.
- What did the transformation in the Cavern of the Elements do to the warriors?
- The Great Beings gave each candidate great power and control over their individual element, and the transformation was thorough enough that every part of each subject was affected and they bore little physical resemblance to their original Glatorian or Skrall bodies. They retained their identities and names, which let them assume political authority over their tribes immediately afterward.
- What happened after the Element Lords were created in the Cavern of the Elements?
- The Great Beings armed the new Element Lords with armour and weapons fitted to their elements and placed them in control of their corresponding tribes. The seven lords ruled together in relative peace for thousands of years until the discovery of an Energized Protodermis spring near Iconox ended the consensus and led to the Core War.
