Interesting. I like this beginning and I have to admit I let out a huge sigh at two things. One, you can actually string a coherent sentence together. More than that, your writing is fluid and mature and frankly you're really just very good at it. Second, your story isn't the typical, butchered type of fanfic that somehow fills this section to the brim. Original is such an ambiguous word but frankly, for lack of better one at the moment, I'd say your story is very original. It's good. Honestly I'm very happy to see a writer like you come and stir up these cobwebs because I'm getting kind of bored of the stereotypical jumble that far supersedes stories like this.

Now, I don't know much about Labyrinth and The Sandman but given the setting I'm assuming I don't need to know too much detail. Given your notes at the end though, again I assume you'll let me know all I need to know.

I like the setting and the fact that Relena's included (Heero's wife no less) and that there's no spontaneous bashing. The plot you've set up as well is unique and you've caught me on a hook with this Purification conflict. I like the connections made and the tension that's soon to come in the future between all the usual characters. I agree with the merging of series, it's hard to truly put them together without extreme AU and have a believable, polished story. I urge you to continue and I can't wait to see how you turn it out :)
