I think finding a White Mage soul stone -- either in an Amdapori ruin or sheer luck kinda like the SCH quest. I think helping a scholar who happens to beworking on Amdapori history is most likely for a "regular" adventurer on a bodyguard quest.
Though even if you do get a white mage soul crystal how will one learn without a teacher?
Unless the soul crystal has been attuned to you going to the CNJ guildmaster might end up with him taking it from your possession.
The closest thing I can think of is working with a amdapori historians to extrapolate as much knowledge of WHM and CNJ and try to replicate it. But who knows the consequences of such actions. Such experiments must be away from Gridania that's for sure
