Only one thing I didn't understand: "orange tent" - is it red or brown?
I hope to see more reviews from you of the same quality! If there's something to tell, please share it with us!
My guesses regarding your questions (the author may provide his own answers later; he is also registered here):
The Sphere of Inhibition, which somehow ends up in your backpack - that's actually better, because sometimes you defeat someone, and then in the next battle, the spell suddenly doesn't work because, for example, a Cloak of Resistance was automatically put on you.
The unnecessary fairy for defeating Nimue: maybe it was needed in some old version, or maybe the message given by the Seer at that time is important - this sometimes happens in RPG maps.
