Lodestone Aeternum

In Gilbert's final book, he makes reference to a mysterious fifth essence, one that links all bodies together in harmony — for the heaven of philosophers, as of theologians, must be gentle, happy, and tranquil, and not at all subject to changes. I seek to discover whether azoth might be the universal aether on which magnets interact, that invisible yet measurable force. Or is azoth a new tool for the aforementioned interaction, granting the bearer a new form of manipulating this aether which was otherwise hidden? Perhaps the properties of magnets crafted from Aeternum-mined material are different in their effects. The miners at Letum's Pick have spoken of quality ores from their mines... I must inquire further.
