I just bought a loaf of bread.

The Lady of the Lake, her arm clad in the purest shimmering samite held aloft yeast from the bosom of the water, signifying by divine providence that I, Kandrathe, was to bake that bread. THAT is why I am your baker.

Strange women lying in ponds distributing yeast is no basis for a system of baking. SUPREME baking ability derives from a mandate from the masses, not from some farcical aquatic ceremony. You can't expect to wield supreme baking power just 'cause some watery tart threw a loaf at you!
