So with 3.2 I started reading a little about Minfilia's past and the events from starting in Ul'dah in 1.X. One thing that caught my eye was in the Tales from the Calamity, it sorta explains why Minfilia changed her name but I was still a bit confused about this. I think I remember it was also explained in 2.X+ around the time when F'lhaminn was being introduced, but since I didn't play 1.X I think I didn't really understand what was being discussed.

So from this story released during ARR aniversary it says,

Her father’s Garlean spymasters still sought Ascilia for her father’s betrayal, but no one would seek “Minfilia,” an Ala Mhigan orphan adopted by an Ul’dahn woman seeking to fill the void left by her lover’s death.
What is this telling us exactly? I'm guessing it means that Minfilia's farther betrayed some Garleans and now they were searching for his daughter for revenge. Is there more information I can read about what Minfilia's farther did?
