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

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

The Tideprism is not a metal warship covered in crystal, nor is it made from ordinary gemstone material. Its entire body is grown from a cultivated **crystal-metal composite**, in which crystalline mineral domains and metallic phases develop together as one continuous structure.

The metallic component does not form conventional armor plates, frames, pipes, or machinery. Instead, metal-rich mineral phases are distributed throughout the crystal lattice, reinforcing major growth boundaries, conducting energy, stabilizing resonance, and giving the enormous vessel structural strength far beyond that of ordinary crystal.

Its forward body grows into a massive fused seed-point, where dense crystal and metal-bearing domains converge into a highly coherent structure. Rather than carrying a conventional main weapon, the vessel can align this forward lattice and concentrate sustained field pressure through the material itself.

The broad central mass serves as both fortress structure and defensive volume. Incoming force is redistributed through intergrown crystalline domains and metallic reinforcement paths rather than absorbed by separate armor layers.

At the rear, several huge crystal generations grow along different crystallographic directions. These are not engines or propulsion pods. By changing field bias through the conductive crystal-metal lattice, the vessel can alter the conditions around its own mass and move without visible exhaust or mechanical thrust.

Its deep blue-green regions mark dense mineral-metal roots, muted aquamarine defines the dominant crystalline growth, and pale sea-silver appears where metallic content becomes richer along facets, boundaries, and newer growth zones.

The Tideprism is therefore not simply a crystal ship. It is a **3.2-kilometer cultivated crystal-metal fortress whose mineral lattice and metallic phases function together as structure, armor, propulsion medium, energy network, weapon system, and repair substrate.**
