What Came First, the Drake or the Egg?

I'm researching the applications of drake essences to my work as a physician. I think they could be a panacea for a host of maladies!

I need someone to go south to the Singing Ridge and get me some.

Willing to take my temporal phase modulator and use it on the nether whelps that hatch from the nether drake eggs? Retrieve the essences from whatever they turn into.

Which, I might add, I'm not certain of what that will be as we're using some pretty dicey, time and space modifying tech here.
