[@Lovejoy] right, trying to write.

Actually, it's not just Lady Adrestia Phaidros thta was known.  Since the two Lanostrans that looked after Zt as a tiny kid were members of the Lady's Anger...Ziotea /herself/ was probably known about, though she was decent at hiding -- and it wasn't worth it to track down a child they thought killed or taken.  So even "Elpis" might be enough to give her away, but she will leave her full name.

how to do this...

I know Ziotea would have asked more about what exactly happened to the nation of Omestris.  She would ask how Essa left the Inquisition, though probably not how Antonin is involved.  She'd probably ask why the ruins are worth keeping -- and maybe a little about what Omestris was like before it fell.  No idea if Essa would have answered any of these questions.
