Hey if you want a native proofreader, I would LOVE to help!! No payment or anything, I'm just bored
I'd say "We know that most of you are illiterate" on the first page first chapter.
I'd remove "harsh" from "harsh reality".
Capitalize The Institute for Chest Standardization as shown.
golden *chests not chest on that fourth page first chapter.
"for gold coins and other treasure, and of course (etc). Add that comma.
Page 5: "fill them or don't."
"gold chests must always be filled with gold."
"and if you don't have any gold, melt the chest down, idiot".
"If you ever encounter a chest that does not match these qualifications"
"He uses an unknown red metal"
I'll do other chapters later
