Ability to see the future: Loose plot thread?

[Cassar]

They are, that's literally what the Astrologians are doing. Both Ishgardian and Sharlayan, on different scales; Sharlayan is more aimed at personal fortunes while Ishgardian reads for broader movements. Each of their schools having a relative lack of detail might actually be a benefit, considering how badly Mikoto is steered wrong by hers.

I haven't done the Astrologian quest lines and I don't know much about them. Do they also predict the future using the echo?

Regardless, I think that having an ancient (or even better, a group of ancients) who has the ability to see the future would be a neat way of closing this little plot thread, at least for me.

Who knows, maybe one of the members of the 14 is responsible for that, something similar to Words of Lahabrea. We still have many Ascians whose real names and jobs remain completely unknown to us. Maybe they could throw in Cassandra from the Greek Mythology as one of them.
