Damn... even though Portuguese is very similar to Italian i have a hard time reading that... used google translator and actually learned new words "bueiros"= "manhole"

It's fine for you to write in italian, google translator has your back for anyone that wants to read your stories

I like that you are writing about beings living in the sewers, i've only looked inside a sewer once and it was terrifying, it's like a whole new world down there! And have you seen those crocodiles that live in the USA sewers? How the hell does that happen!!!
But rereading the whole text you are making a comparison between the beings that live in the sewers and the oppressed people we have in our world right?
