I love that you did this. I think one of the most intriguing things to me was they spoke in one of the audio dramas about the Timelords being concerned because the 8th Doctor was in possession of "the Moment." That automatically made me think of Setsuna!
Poor Dr. He actually has a lot in common with manga Saturn since she had to wipe out the Moon Kingdom. Having the power to help and destroy. Crossovers are so fun. Especially those involving the two pairings I actually care about: Haruka & Michiru and The Doctor & Rose.
Sailor Gallifrey!
Great job!
