Oceanic Tectonic Plates of Caemothas

Beneath the vast oceans and enchanted seas of Caemothas lie the world’s oceanic tectonic plates—massive, dynamic crustal sections that drive deep-sea volcanic activity, hydrothermal rifts, and elemental disruptions. These plates differ from their continental counterparts in that they are thinner, more mobile, and often serve as the foundation for magical trenches, rift zones, and sunken ruins.  

Plate Characteristics

Thinner crust, rich in basalt and magical minerals

Define subduction trenches, spreading ridges, and leyline-charged hydrothermal vents

Known to produce both natural earthquakes and magically induced seafloor ruptures

Major Oceanic Plates

 

Niasari Plate

Location: Beneath the Niasano Expanse and Madness Reef

---

Tectonic Type: Divergent and subduction hybrid
Key Features:

Deepest trenches in Caemothas

Magical hydrothermal activity, abyssal creatures, and leyline whirlpools

Bioluminescent kelp forests and spell-charged coral reefs

Site of frequent time dilation distortions reported by expeditions to the Abyssal Maw

Calberan Deep Plate

Location: Southeast of the Domain of Calberg
Tectonic Type: Subduction zone and arcane fault system
Key Features:

Highly unstable and magically reactive

Home to collapsed ruins and underwater volcanic rifts

Void slivers and arcane implosions reported during the Eclipse Epoch

Movement: Northward creep of ~3 cm/year

Kingsgard Plate

Location: West of Bariculbos, beneath the Kingsgard Ocean
Tectonic Type: Spreading center with transform faults
Key Features:

Long mid-ocean ridge system

Ancient volcanic chains and drifting reef platforms

Consistent magical upwellings that feed into warm current gyres

Movement: Northwest drift of ~2.5 cm/year

Vakalouan Plate

Location: Beneath Vindamosa, Yatu Vakalou, and the Galtawa Sea
Tectonic Type: Stable transform boundary
Key Features:

Most geologically stable oceanic plate

Coral rings, shallow rift valleys, and magical equilibrium zones

Presence of healing leyline pools considered sacred to the Sea Druids

Pyraethon Plate

Location: South of Iozoles, extending into deep volcanic plains
Tectonic Type: Active divergent zone
Key Features:

Home to magma flows and deep crustal vents

Arcane fissures believed to connect to the Plane of Fire

Fire Primordial energy frequently radiates from arc-wells and flame-veins

Site of the Magmatic Leyline Wells, believed to power ancient forge-cities

Hasslian Plate

Location: Beneath Hasslis Waters and eastern trenches
Tectonic Type: Chaotic fault convergence
Key Features:

Unpredictable seismic spikes and planar shear events

Arcane storm centers and elemental sea disruptions

Suspected elemental rift linked to a dormant Primordial of Storms

Saxum Oceanic Extension

Location: South of Mauvaiscolac in the Frostmaw Sea
Tectonic Type: Subduction zone under polar glacial layers
Key Features:

Underlies massive iceberg shears

Freezing vent activity and seismic glacier shifts

Residual elemental influence tied to Xerathor, The Frost Seraphid

Frossen Plate

Location: Near the northern Artic Abyss
Tectonic Type: Dormant with passive transform stress
Key Features:

Ice elemental residue and faint leyline interference

Believed by scholars to be a glacial landmass fragment from before the Eclipse Epoch

Tectonic Fault Types Found Beneath the Seas

Spreading Centers (Red dashed lines on map)

Magical & Elemental Phenomena

The Forgehubs

Forge of Fire (Iozoles): Fueled by deep subduction heat and the Plane of Fire

Forge of Earth (Brekax): Lies above a titanic tectonic pressure point

 

Elemental and Magical Influence

Magmatic Leyline Wells: Deep under Pyraethon and Niasari Plates

Abyssal Convergences: Madness Reef trenchline collapses

Arcane Subduction Rifts: Calberan Deep’s unstable trenchlines rupture into flashes of planar energy

Elemental Correlations

Fire: Pyraethon
Ice: Frossen, Saxum Oceanic Extension
Storms: Hasslian
Balance: Vakalouan  

Historical Events

The Shattering of Thul’mora

Occurred on the Calberan Plate during the Eclipse Epoch, scattering a wave of planar ash across the ocean floor.  

The Abyssal Maw Collapse

A trench implosion on the Niasari Plate caused a magical time rift still active to this day.  

Known Exploration Zones

 

Madness Reef Expedition

Of 14 sent, only 3 returned—driven mad by visions of a slumbering leviathan beneath a black sun.  

Saxum Probe Drill Team

Discovered a hidden magma chamber beneath glacial ice, but vanished after their final transmission screamed about "ice that bleeds fire."  

Final Notes

Scholars, sea druids, and elemental cartographers believe these plates are not only tectonic in nature—but spiritually charged. The tremors and shifts may be echoes of ancient Primordials, or remnants of the Eclipse Epoch that fractured the seas and the skies alike. The deeper one dives, the closer they come to the truths best left drowned.
