Thaumcraft 4.1 Aspects

Okay, most aspects are pretty easy to find, except for one: Auram

Has anyone else come across this or am I just missing something? I have tried and tried to find items that have Auram in it so I can create stuff like wand caps but finding products that have Auram in it seems impossible to me.

If anyone can shed some light on this that would be greatly appreciated and I will update the ftbwiki.com site so others like me can know exactly what items have Auram in it.

Thanks!
