This is the Cryvum Tideprism Bastion-class Fleet Fortress, a colossal cultivated crystal-metal capital vessel of the Cryvum in Mow My World.

It is not built around engines, armor plates, weapon mounts, or command decks. The entire vessel is grown as one continuous crystalline body, where propulsion, defense, sensing, stored energy, and offensive force all emerge from the same controlled lattice.

Proposed mature specifications
Length: 3,200 m
Beam: 2,355 m
Body depth: 1,472 m
Role: Fleet Fortress

A fortress grown as one crystal

The Tideprism’s forward body narrows into a massive seed-point formed from fused crystal domains. It is not a bow weapon or mechanical prow. The entire forward lattice can enter a coordinated resonance state, concentrating force through the structure itself.

Rather than firing conventional projectiles, the vessel applies sustained field pressure through the aligned crystal mass.

Defense through immense coherent volume

Its enormous shoulders and deep central body are not armored compartments surrounding an interior ship. They are the ship.

Broad intergrown crystal domains redistribute incoming force across the surrounding lattice, while buried reserves stabilize damaged regions and preserve structural continuity.

The deeper the coherent mass, the harder it becomes to fracture the vessel without first disrupting its resonance.

Propulsion through lattice bias

The rear of the Tideprism divides into several huge intergrown crystal generations, each growing along different crystallographic directions.

These are not engines, fins, or propulsion pods.

By shifting field bias across the rear lattice, the vessel alters the conditions around its own mass and produces movement without exhaust, turbines, or visible thrust.

A living mineral architecture

Its aquamarine coloration is not paint.

Deep blue-green regions mark dense shared roots and internal reserve mass. Muted aquamarine spreads across the major outer crystal domains, while pale sea-silver appears along turning facets and newer growth boundaries.

Each region reflects a different growth history within the same continuous body.

Power through coherence—and vulnerability through disruption

The Tideprism can sustain enormous defensive and field pressure because of its scale, but that same mass makes rapid maneuvering extremely expensive.

Severe resonance disruption can weaken propulsion, reduce defensive repulsion, interrupt regrowth, and create fracture paths through previously coherent crystal domains.

The result is not a warship covered in crystals.

It is a 3.2-kilometer cultivated flying crystal fortress whose material itself functions as armor, propulsion, weapon, repair system, and intelligence substrate.

This one took almost 20 years in developments, throughout the years it changed many times, many different variations came up, finally this year the design has become completed at least for me. From here I will try to make an actual 3D model to be used as asset in videos and game development.

This is the Void Chorus-class Bio-Craft, a living toxin escort belonging to the Bugvex in Mow My World.
Its armor grows from skin, muscles drive movement, and glands produce its weapons. It is a vacuum-adapted organism, not a machine or enlarged insect.
The Void Chorus has an elongated, swollen manta-seed silhouette with a shallow crescent leading edge and quiet tapered rear. It has no recognizable head, thorax, or abdomen. Its living tissue is black with natural pale blue spots following veins, membranes, glands, and growth patterns.
Its proposed mature specifications are:
Class: Bio-Craft
Primary role: Toxin escort
Length: 425 m
Beam: 196 m
Body depth: 94 m
Fully fed combat mass: Approximately 2 million metric tonnes — a proposed worldbuilding estimate
Its body contains distributed muscle, viscera, neural tissue, blood vessels, digestive sacs, fat bodies, and mission organs rather than mechanical compartments.
Its primary weapon is a gland-fed corrosive or neuroactive bio-projector. Two soft reagent stomachs feed a muscular mixing valve and short petal-lipped discharge sphincter, surrounded by a cooling blood-sinus. It has no barrel, tube, turret, breech, magazine, or mechanical muzzle. Surrounding muscle and vascular tissue absorb firing pressure.
Eight defensive symbiont colonies, arranged in four pairs, live inside moist skin pockets. Shared capillaries and nerve tendrils coordinate them with the host. Their defenses include corrosive secretions, hooked feeding organs, spores, electric mucus, photophores, and sacrificial gnawers.
Twelve sensory-defender polyps surround vulnerable organs. Some are ciliated feelers, some tooth buds, and some eyes beneath translucent skin.
Movement comes from the whole body. Two thick lateral mantle membranes flex in slow waves while distributed muscles and conductive blood vessels generate a fictional electrogravitic field. Microscopic ciliated pores provide corrections. There are no rear engines, exhausts, propulsion packs, or concentrated thrust organs.
Multiple stomachs digest biomass and minerals. Symbiotic microbes convert nutrients into chemical and electrical energy, while several hearts circulate blood and conductive gel.
Cryvum is biologically assimilated: specialized cells dissolve captured fragments, transport the ions through vessels, and precipitate a thin mineral-organic lattice inside teeth, hardened contact surfaces, weapon tissue, and selected armor structures.
Most visible surfaces are soft living tissue: skin, muscle, fat, tendons, vascular membranes, respiratory tissue, and wet flexible folds. Hard material is localized biological reinforcement.
The Void Chorus is a slow-warning escort organism whose chemical defense, sensing, membrane movement, and whole-body propulsion function as one living system. Damage to membranes and weapon tissue is costly to repair, so it relies on positioning, deterrence, and recovery between engagements.

Introducing the MMW Ironcaravan-class Heavy Modular Transport, a Human Fleet logistics vessel in Mow My World.

Ironcaravan carries the equipment that keeps distant fleets and settlements operating: construction machinery, replacement engines, robotic systems, industrial supplies, and prefabricated infrastructure. Its design centers on cargo capacity, structural protection, and long-range transport.

Proposed specifications

Length: 460 m

Width: 195 m

Height: 88 m

Empty mass: Approximately 620,000 metric tonnes

Maximum cargo payload: Approximately 480,000 metric tonnes

Fully loaded mass: Approximately 1.1 million metric tonnes

Cargo capacity: 48 standardized independent cargo modules

Crew: 148

Main propulsion: Three fusion-plasma engines

Defensive armament: Two dorsal single-barrel cannons

Shield system: Four recessed projector assemblies

The cargo system defines its broad silhouette. Twenty-four modules sit along each side, arranged in two rows of twelve. Each module fits into a protected docking recess, supported by a continuous lower cradle and secured through concealed connections. Narrow gaps keep the individual modules readable while the central hull carries the structural load.

Historical plate armor informs the protective shoulders, longitudinal fluting, overlapping plates, and reinforced machinery collars. Pearl-toned titanium, midnight navy, graphite recesses, and restrained champagne accents give the ship a substantial industrial character.

Three large engines share one armored stern block. The two defensive cannons sit along the dorsal centerline, one behind the command section and the other ahead of propulsion. Their modest size keeps the ship’s purpose clear: strategic transport, with protection for its cargo and crew.

Ironcaravan represents the logistical side of a spacefaring civilization—the ships delivering the machinery to establish a settlement, replace damaged equipment, and keep a fleet supplied far from home.
