Department of Improbable AUs

Headed by the Antigravity Apple, the Department of Improbable AUs deals with AU fics that aren't so much set in an alternate universe as in a completely different one, where the only recognisable elements from the canon are the characters names. It is not known whether or not the DIAU still has any active agents. It isn't clear just what they do in their missions, but it's possible (probable?) that they act similarly to the Department of Implausible Crossovers.
