I didn't have time to finish it off, sadly, but I was going to do a Savage Bard 7/Ur-Priest 2/Geo 1/Sublime Chord 1/Geo 9, advancing both Ur/SC intermittently (So 5 levels per class).

His whole schtick would have been double 7ths (From the Wizard/Cleric lists!), using drifts to keep him out of the firing line and using his spells to end fights quickly, since he didn't have many spells per day.
