I finally drew up some of the important crystals mentioned so far in my galaxy. Ill be making more as I find my notes on them or discover more through RP and chats.

Allurite - Found mostly in the Pollussus Nova, this crystal is rare and thought to be extra dimensional in origin. This material converts energy into arousal and pleasure. Through sophisticated engineering, the Argons have designed a system which uses Allurite to turn pleasure back into pure energy. It is the core of any Argon sex energy star drive.

Mesmerite - A rare material found on worlds once controlled by the Sirens. This material comes in may colors and amplifies a Siren's telepathic abilities. Sirens must find one of these crystals and attune themselves to it as part of a right of passage and coming of age ritual.

Chthonic Crystals - Found only on Chthonian planets, these precious gems are formed in the super compressed depths of a gas giant. These stones posses elemental energies unique to their planet of origin, most notable being the Temporan fire crystals which Voluptrians mine for their photonic weaponry.

Aegis Stone - Originally found on silicate planets such as those in globular clusters, Aegis stone is now synthetically produced by several races. When energy is beamed into one of these crystals, it generates a field of force nearby. This is the core component of any ship or personal shield system.

Graviton Cores - Deep in the core of any planet in the Starfish Galaxy is a material drilled for its gravity producing properties. This is the core component of any graviton generator.

Energite - An extremely rare and unstable material that occasionally drifts into the Pollussus Nova through the inter-dimensional Terminus Wormhole. Energite's exact origins are unknown but it is believed to be a solid form of pure energy which can be used to power any device or ship for months. The crystal dissolves as it looses energy and large crystals have a chance of exploding violently when depleted.

Nautilus Hearts - These crystals can be found across Starfish galaxy and are believed to be the remains of an extinct space fairing creature. Until recently, these stones were only used as a precious and exotic gemstone, but some technologically advanced races have discovered its vast data storing capabilities.

Oculoids - These stones look strangely similar to eyeballs and in fact they are living creatures. Oculoids inhabit the silicate world of Oculus and hunger for knowledge. They manipulate their surroundings with small beams of telekinetic like energy but quickly deplete their energy reserves in the process. When their energy is gone, Oculoids do nothing, and appear lifeless as a stone until re-energized. Oculoids cannot speak, but can communicate if connected to a computer.

Entangled Crystals - Found scattered across the galaxy are rare Entangled crystals which initially form together, but if separated, can beam or receive energy from its mate, anywhere in the galaxy. Energy is thought to be transfered between the crystals through a pocket dimension that they are connected to, and as a result energy transfer is lossless and instantaneous.

Augmentium - A strange crystalline growth which is found across the galaxy in different forms. The energy aura that surrounds this substance is known to temporarily change lifeforms in various ways. Some cases have been known to change the size of body parts, transform lifeforms into different creatures, enlarge them to be giants or extremely small, and even turn animals into intelligent humanoids.
