Mithral

Mithral is highly sought after for both is practical and ornate uses. It is a coveted choice for use in jewellery and gilding clothing. Mithral is also praised for its use as armour and weapons, as it is flexible, light, and also strong.
Mithral ore appears as a silver-and-black mineral in its natural form, and becomes a shining silvery-blue when it is forged.
