Forgers, like Shai can used essence marks to rewrite their history, transforming them into another version of themselves. Yet how do they maintain control of their original selves? Though they would have both histories, the central self with their essence marks on is that of their alternate self, why would their alternate selves yield control over to the main self instead of continuously stamping themselves?

The alternate selves might be wrote to be malleable to the desires of the original self, but is that the case for all essence marks that are meant to be used as an aid to oneself?

In Scadrial during Wax and Wayne's times, there's restaurants looking for Bendalloy and Cadmium mistings, likely to improve waiting times whilst waiting for a meal. Given how expensive the metals are, at least Bendalloy, how could they be used on such a large scale for restaurants?

In The Emperor's Soul, did Shai actually go train with the Tellulu people to gain experience for her essence marks or was it all fabricated and she never went there?
