You misunderstand the nature of seercraft, far-shooting Graham. Although the gift is bestowed upon mortal eyes by Phoebus Apollo, it is not a means by which to contact the gods directly as one would when offering up prayers and supplications. Rather, those who are gifted in such a way gain insight as to what certain signs portend, that we may then know what approach to take - or they may be gripped by visions that tell of what has been and what must be as decreed by fate.
