Nodding agreement, he continues drinking. "Very, very appreciated. I could get used to this."

That thing will never work again. But I got thinking...about how it was that Time Lords used to travel so easily across realities, and what part of the TARDIS's tech was most responsible for that. So I took the principle of the canon, and the oh-so-very humaness of it, hooked up the right pieces to the transdusive cable beneath the time rotor, adjusted the variable calculations for the cross-over, gave them a wider range, raised the harmonic resonance of the field modifier..." he shrugs, "And, here we are. I do seem to have forgotten to adjust for the extra power needed, but that will soon be set right here!"
