From the journal of Theodore Markes, Renowned Explorer:

"Primordials have an interesting, albeit seldomly spoken bit of folklore. Creatures formed of elemental energy that once roamed Aeterna before the coming of the Empress and the Pantheon. Though all records state they went extinct several millennia ago, my encounter with the treant Lotus may suggest otherwise. She claims to be younger than me, which is certainly hard to believe; but she acts like a young woman fresh out of her teenage years, so who am I to question it. I've not met another potential primordial other than Lotus, so I must keep an eye out for them in my future travels."
