Who is that boy at the beginning of chapter 1 ?
In chapter 7 we can see the conversation between Eivana, doctor, martillo and old man.
Is this old man is a Quema Tormenta?

very unlikely, because Quema Tormenta had very Long hair
And that old guy has hardly 'any' hair

Even tho it's a diff Universe (Sort of) the Characters are all playing diff roles, but Look the same
as in the Aww series
