I must warn you, though, "Alternate Caretaker" is a very long, slow-building story that follows closely canon facts for the first couple of chapters and goes AU only gradually. It isn't even half-finished yet, either.

Re: Maquis
Now, I must admit that of all the "newer" Star Trek series, DS9 is my absolute favourite. ("Enterprise" I don't even consider Star Trek.) But there are three major things that I really, really hate:

1) Kira's utterly failed love life. That she had to end up with Odo, of all people (especially *after* what happened in "Children of Time", I found it absolutely unbelievable), only so that in the end she would get dropped by him and had to be Understanding Woman(TM) for the male's Greater Purpose(TM).

2) Sisko's semi-divine origins, aka the fact that the PTB just didn't have the balls to allow a Starfleet Officer to be a religious symbol at the same time. He'd only have been a symbol, for Pete's sake! The religious *leader* would have remained the Kai, whoever it was at any given time!

3) The way Sisko turned against the Maquis, after some half-hearted sympathies, especially his obsessed pursuit of Eddington.
