💎 Crystals

Crystals in Hetra are among the most versatile and sought-after materials on the planet. From powering cities to enhancing living beings, they sit at the intersection of nature and technology.

Hexicules

Hexicules are core crystals composed of high-energy magic cells — live inanimate beings in their own right. They are extraordinarily common and can be found virtually anywhere across Hetra.

Appearance

Hexicules vary greatly in size. Small ones are often shaped like a heart; larger ones can reach nearly the size of a drawer. They sometimes naturally group together in formations of up to eight — three small and five large — forming what are called Hexicule Clusters, or a Supercluster.

Properties & Mechanics

• Hexicules are incredibly dense due to their high molecular structure, making it physically impossible to scratch or dent them under normal conditions — though they are not indestructible.
• Their energy regenerates at an extraordinarily fast rate, meaning recharging is rarely a necessity.
• A single Hexicule outputs a full charge of 64,500 eXpH.

When Modified

• When two or more Hexicules are combined, they lose 20% of their durability and their regenerative properties slow significantly — taking approximately 2.5 hours to self-repair.
• When modified into batteries, Hexicules lose 30–50% of their base charge, outputting approximately 22,400 eXpH.

💡 The Hexicule energy market is one of Hetra's most dominant industries — engineers and artificers have spent centuries trying to minimize energy loss during modification with only marginal success.
