Narvin, you're a Time Lord. You may not be good with individuals, but you can see clearly, if you focus, how the life and characteristics of another can affect a world. [He holds up his now half empty snifter] It seems that among us there were few adequately prepared to deal with wide-scale invasions, form unions, organize tactical resistance. Ah, [he perks] but it seems that a human could. A human with no ambition for power, but a thirst for knowledge and the desperate will to protect. Intrinsic behaviour that remains despite documented manipulation of his personality and reorganization of his memories. A president like that could win the war, restore Gallifrey to its former glory, integrate it into the political structure while maintaining its culture through gradual introduction of elements, and all it would take is one run through a chameleon arch, an agreeable House to falsify their records, and elements of memory manufactured from the Matrix.

[He tilts his head at Narvin.] A very probable way to win, if you consider the trails of consequence, with the sacrifice of a single human. But you wouldn't do that, would you? And should you? No. If we can't even choose our Presidents without a dependency on nostalgia and without a shred of true practicality, from our own stock, do we really deserve to win that war? Would it be worth it?

How would Ardent's characteristics, as they are, affect his world? We already know what he's capable of aboard the Barge.
