Yeah, the author gives names to random cities that the reader won't even see so I think lacile's brother not being named could have a deeper meaning here
@Baksz A couple chapter ago during the last roundtable meeting in chapter 126. They said biove was the emperor of a kingdom close to the granaga dominion of light
So laciles grandpa was one of the heroes... Makes sense why he was hiding in the mountains with lacile.
And lol at gladias saying what we were all thinking when lacile got saved by the power of friendship
