Basic ideas for the flavor of the mystic and savant.
-Use innate sorcerous power to channel and invoke the might of natural forces, god-like beings and cosmic entities.
-Draws power/spell list from mantles, just like an ardent.
-Combines innate mystical power with occult or hermetic knowledge gleaned from study and apprenticeship. Savants learn about the universe's working to better manipulate it with their own magical energy.
