Ysalwen has gotten up before him, looking for a particular book on mathematics and another on welding.

By the time he hits the stacks she's started working equations on her tablet, brow furrowing as error messages populate her screen.

Missing boundary conditions are a pain. Once she has those sorted, however, she sets the tablet down to let the simulation run, then turns to her welding book.

Methods, temperatures, cooling profiles -- all of these are of great interest to her. Particularly in thinking how magic might aid in each desired approach.
