Hell of a claim to make that she has more power than the royal family, but then again, gramps did kind of twist the royals hands a bit in an earlier chapter with...um, something about trade and economics (in chapter 171), and Tia is very much in his good graces, not to mention all the other exceptional things about her.
You know what, never mind, the claim is pretty believable.
Side note, I wonder if Perez and Ramona were a love match... Maybe for Ramona, but Perez?
Also, after 171 chapters it is soooo cathartic to finally get the ball rolling with this matriarch business. Tia never got this test in her past life, right? Feels like new territory, is all.
