Throwing out some ideas:

Relationship Building with Dimetria is a definite.

Studying Pattern Books/Communing with Ariadne; something by which she gains further understanding of Ariadne's "everything-is-thread" mysticism. This could kinda dovetail with her Artificer/Ritualist advantages, since obviously she can't just learn more powers.

Her sort of "giving back to the community" could be Teaching Classes at the School, though I'm not positive what the conferred benefit would be. Maybe this just accrues goodwill with the population at large, maybe parents of the children have contacts or connections that could help Kal in various ways.
