[Martial arts..? She assumes that that's either battle techniques, or yet another type of magic - one that's transferable, if so. What Eva says next, however, is concerning, so she focuses on that part rather than thinking of a way to politely decline the offer (she can't allow herself to even fight defensively - how selfish would that be, when her people responded to their victims' attempts to defend themselves with even crueler brutality?).]

Is it a reset of sorts? Maybe those who return here after being called home have to learn their magical skills again from the beginning.

[How demoralising would that be! She can imagine how shattered she'd feel if the became an accomplished healer, able to restore people from even near-death, only to find all her progress gone after such a recall!]
