The worlds of Jaern and Cahyali and the multiverse as a whole have many unique materials that require special definitions. Most of these materials can be found around the world and used by adventurers for many things. In addition, one can also find most mundane materials such as gold, iron, steel, diamond, etc.

A super strong, almost unbreakable metal that is a favorite of dwarven smiths. Adamantite's appearance is that of a lustrous and silvery metal, ranging in exact shade from a dark gunmetal to a bright silver sheen. Its most defining feature visually, however, is the shifting green sheen that flows over its surface when properly purified, alloyed, and forged.

Adamantite can be used in an alloy to create high-quality weapons and armor - its pure form is difficult to forge, exorbitantly expensive, and most generally prefer to alloy it with steel, titanium, or other more workable metals. Anything made of pure adamantite is likely decorative or ceremonial.

There are many ways one can alter or enchant mundane metal to transform it into a magical material - depending on the process, the results can vary wildly.

• Arcane Silver: Created via specific forging processes guided by mages, this variant of silver channels magic far better than its mundane counterpart. This makes it better suited for use in spellcasting than other metals. Arcane silver, over time, gains a slight colored shimmer which matches the magic it is used to cast.
• Celestial Silver: A variant of silver forged and enchanted in the Celestial Planes. Can only be found in very small amounts in the mortal realm, but grants some protection against the forces of the divine. Identifiable from mundane silver due to the fact that it gives off a faint light.
• Chaos Iron: Exposure to chaos magic can destabilize a metal. It becomes multicolored, and begins to channel unstable elemental power. The nature of this power is unpredictable day to day, but some adventurers prefer this…
• Crimson Alloy: A certain blood magic ritual can give metals a strange semblance of life, as well as parasitic properties. These metals turn red, in full or in part, and drain the vitality from anyone who uses them in order to become sharper and more deadly.
• Fey Iron: After being exposed to the mystical energies of the Dreaming, this iron gains a gold, blue, or green shimmer and no longer damages creatures normally harmed by iron. In addition, its enchantment seems to shield the mind from charming or manipulative effects.
• Living Metal: Powerful necromantic or psionic rituals can imbue regular metals with regenerative power, much like a living organism's natural healing. This can be done to a variety of metals, and has no distinctive appearance - one can tell living metal when it begins to knit itself back together after being damaged.
• Lycan Steel: Appearing like regular steel with intricate runes carved just beneath the surface, the secrets to crafting lycan steel are known only to the werebeast tribes of Jaern, and require forging under the light of one of the two moons: Mournglade or Obenar. Depending on the ritual performed, armor made of this metal can greatly enhance physical prowess.
• Necrosteel: Exposure to blighted energies can change normal steel into necrosteel. This metal has a dark maze-like pattern similar to Damascus steel, and is capable of draining the life from others to heal its user.
• Warped Steel: Exposure to dimensional and spatial magic can make a metal twist into this. From the right angle, it appears like the starry sky. It is capable of anchoring creatures struck with it in their planes, preventing teleportation.

The name of this metal derives from an ancient deity with two faces, reflecting its dual nature. Depending on the details of its forging, ismudium can resist force originating from up close yet be incredibly weak to attacks from afar, or vice versa. Its appearance resembles brass, but is a little more silvery.

At a glance, it is hard to tell which weakness an ismudium piece has, but close inspection reveals that melee-weak ismudium is a little more lustrous than ranged-weak ismudium.

This metal is light, both in color and weight. It has long been used in elven communities to forge lightweight weapons and armor, fit for speeding through thick forests with agility and dexterity. Its appearance is almost pearlescent - an extremely light-colored metal that ranges from silvery to something akin to rose gold.

Mythril veins are often found in large forested areas, pointing to why elves were the first to discover and use it. It is said to be equal in strength to a good steel, but half as heavy.

An alloy of lead and terisium, and one of the more effective anti-magic materials in common use. Due to the terisium component, this metal cancels out most magical effects attempting to affect it - whether this originates from the tool or armor's user or an outside source.

Silent steel's appearance resembles lead, but the terisium component is betrayed by a prismatic sheen when the right light strikes the metal. It is difficult to forge - as the process can't be assisted by magical means, so silent steel is one of the more expensive materials on the market.
