Artherium

Artherium is a magical material used in the creation of all magic items.

Characteristics
Pure artherium is a dull bronze colored dust, but it is very rarely seen in this form. In applications where pure artherium is desired, it is often purified into a silver gel.

Gold, Gems and other Precious Metals
Small amounts of artherium can be found in many precious metals, most notably gold and platinum. Gold is as much as 1/45 artherium and platinum can be up to 1/5 artherium. Some gems are also rich in artherium, and particularly valuable gems can be be made up of upwards of 9/10 artherium.

Astral Sea
The Astral Sea is home to massive amounts of artherium, but due to the 4-dimensional nature of the plane, and the semi-gaseous state artherium is found in on the sea, it is extremely difficult to gather.

Alcohol
Small amounts of artherium are created in the fermenting process of most sugars. While the amount of artherium created is often to little to even offset the cost of the supplies for fermentation in the first place, but that doesn't stop some desperate artificers from harnessing mead as a enchantment medium
