The mages might find his request a little curious if Kyle hasn't expressed interest in learning Academic Magic prior to this, as Thorne doesn't see High Magic as the standard. Kyle will notice the books are more of a scholarly nature than one that teaches anything regarding methodology or accurate practices. They'll tell him that they're only apprentices so they can't speak to the resources normally available for the Summoned.

However, he may wish to talk to someone in a higher position after the crisis is resolved if he has an interest to see where that gets him.

He can also consider taking advantage of Solvunn's current open borders and simply go there himself, as long as he is going under the guise of helping to investigate. Since Kyle has a reputation as a trustworthy courier and has been helpful throughout this incident, Thorne would allow him to go. Although Solvunn primarily relies on an oral tradition, he might learn information there that wouldn't be available in Thorne.
