Aura (Thaumcraft 3)

The Aura is a field of magical energy prevalent throughout the world. Its origin is unclear. Some believe it is the accumulated life force of living beings, while others believe it to merely be another type of energy seeping in from some other place. The last theory seems to be most likely, as the aura is often found surrounding a node of concentrated mystical energy known as an Aura Node.

Each aura node has a base amount of magical energy it can contain. If this energy dips lower it will try and recharge itself back to the base level. It does this by either borrowing energy from nearby auras, or by being recharged by Infused Ore nearby. Whenever a node is above or below this base number it randomly generates Flux as it struggles to return to it's base level.

Aura nodes vary in strength, size and location and so far four types have been discovered: Normal nodes without any special attributes, Pure nodes that cleanse themselves of Flux, Unstable nodes that generate flux, and lastly Dark nodes that pump forth malign energy.

The Aura can be tapped by a Thaumaturge to power his magical devices and spells. Energy that has harvested in this manner is known as vis.
