So, I haven't read it, but I've skimmed it, and skimming has been enough to tell me that this story takes place in a universe where the EDA Sometime Never never happened.
As with most things I've been posting for the lj Who at 50 ficathon, this was supposed to be much longer... (it was also supposed to be posted last month and involve Kratatoa, but it kind of took of at a right angle to what it was supposed to be and became sometimes else). I'm not marking it as complete on the off-chance that the rest of the plot ever comes together, but I think what's up now stands as is.
