Cyre was home to House Cannith, the humans who possess the Mark of Making. The warforged are their most famous creation, but these living constructs are not Cannith’s only accomplishment. Cannith mines and forges dotted Cyre, and workers constantly unearthed ore, refined it, and shaped it into the latest Cannith masterpieces. When the Day of Mourning came, the metals that were in the process of being refined absorbed the catastrophe’s arcane power. Now, ingots and chunks of this magically imbued substance lie scattered throughout the Mournland. Scholars have termed this material cyrite.
Cyrite resembles steel but is slightly darker. Multi-coloured lines run over its surface and pulse with strange light. It is as heavy as steel, holds an edge just as well, and retains some magic essence from its odd genesis.
Smiths and adventurers value cyrite for its use in weapons and armour. Weapons fashioned from cyrite count as magic weapons for the purpose of overcoming damage reduction. Armour made from cyrite absorbs magical energy and grants its wearer a +1 resistance bonus on saving throws against spells and spell-like abilities. Cyrite shields provide no special benefit.
Items without metal parts, such as clubs, cannot be made from cyrite.
Cyrite loses all its special properties in an antimagic field or similar area.
Weapons, armour and shields that are made of cyrite have the same hit points and hardness as they do when made from metal of a normal sort (typically steel).
| Type of Cyrite Item | Item Cost Modifier |
|---|---|
| Ammunition | +5 gp |
| Armour | +500 gp |
| Weapon | +250 gp |
| Raw Cyrite | 10 gp/lb. |
The above features apply to most examples of cyrite that explorers have discovered. Rumours speak of other forms of cyrite with different properties.
