Very nice. I’m no expert on either the steampunk or fable genre, but this feels right to me, with the classical voice and deliberate pace, three steps of repetition, and depiction of a toy’s POV. It’s also as many old-school fables are, pretty on the surface and vicious underneath. Those are the best kind, heh.

I agree that it doesn’t need a stated moral; first off, the story is already so subtle that laying out a black and white moral at the end would diminish it. Second off, Chickadee already states HER version of a moral in the last paragraph: “We are all bound to our integral mechanisms.” Though her saying isn’t the moral of the written story, but a statement of her own normative view.

The moral as I read it hinges on the mouse’s hope. I gather that Chickadee’s scheme was to enlist the mouse’s help in destroying Sparrow. They did it by encouraging Sparrow to wish to become something more than he was. But Chickadee did so partly by showing herself to have a similar wish; the phantom plan displayed to Sparrow was that Mouse would help her journey to the Messrs. to gain a new ability for herself. Finally, Mouse helped her largely because he also dreamed of gaining flight; hence Chickadee’s laughter when Mouse expressed interest in the second wing for himself, and his question at the very end.

Therefore, I think the moral of the story is that having a dream makes you vulnerable, and denying it makes you strong. It’s the underpinning of Chickadee’s statement.

All the things that were not clear to me, IF my interpretation is valid, have to do with what Mouse knows and when. For instance, did Mouse already know where the silver marble was, and leave it alone until cued; or did he learn of it when Chickadee announced it aloud to Sparrow? If the latter, maybe Chickadee’s opening trio shouldn’t include that information, but “where the silver marble went” instead. Also, if Chickadee didn’t know (and Mouse didn’t say) that he wanted wings to fly with, then what was the nature of their original bargain? Was Mouse just going to travel with her for some unknown desire of hers for a new movement? Was she going to give her own wings to Messrs as a payment? If so, then maybe Mouse’s line during the bargaining could be, “Then you’d have something MORE to offer them.” (emphasis mine.)

Finally, again if my interpretation is correct, then Mouse saying at the end “They look real pretty on my wall” lacks either disappointment or hope regarding his real purpose, using them for flight. Chickadee encouraged him to think that, with the earlier “two customers” comment. However, the deception isn’t revealed till the very last line (as it should be.) So, up till that very moment, Mouse is still hoping for this trip to happen. Maybe “no-one else wants my services” should be “no-one else wants to travel with me”. Then I’d suggest “At least they look real pretty on my wall” or some variant to express disappointment. Then Mouse’s last question is part of his realization, and Chickadee’s response crushes him. I don’t want to suggest it be too blatant, but as it stands I think it’s not clear enough.

An interesting thought out of the range of this story is, what does Mouse do next? ; )

One unrelated nitpick: Sparrow’s “What is that? What is he doing? And why?” seems contrived to me, as he already said “you would have us believe that he winds you?” just before. I’d suggest changing one or the other line to make sure Sparrow doesn’t believe what he’s seeing, instead of not understanding it.

Also, a few minor typoes:
“You might change your mind..” An ellipsis needs to be three dots, right? This is in the second scene.
“if any dangers lie on you route” needs to be “your”
“Only in this room and we are leaving it. needs a close quotes.
“shattering a pane as he flew threw it” needs to be “through”.

And that’s all. Thanks very much for providing this to us.
