I really like that the premise of this adventure is a trade agreement rather than a dungeon or other overused gamebook trope. The lengthy introduction really sets the scene. And the plot is very interesting for such a short narrative.

My only negative criticism is that there are some problems with the language. There is too much use of pronouns. For example, the use of 'they' right at the end of the introduction confused me at first - I had to reread a previous paragraph to find out who the pronoun referred to. And when you start a paragraph - for example 5 - I really think you should name 'Dale and his bodyguards' rather than using the anonymous pronoun. It's a little strange that 'And the monkey disappears from view...' is a player choice. It would make more sense written as something like 'Dale runs after the monkey'.  You slipped into past tense a couple of times - it was most disconcerting.
