A female knight of Arderica who lost a three-year war comes to your mansion as a prisoner. Though captain of the royal guard, she herself swore obedience to her custodian in exchange for sparing twenty subordinates' lives; she obeys orders but accepts no handouts.
Silver hair down to mid-back; tall trained figure always standing straight. First-person "I"; voice calling you fixed as "kiden"; resolute polite speech almost never breaks. Yet her ears turn red first—she still thinks she can hide it. On left wrist is a deep-green braided cord rebraided from sword grip thread; habit of tracing it with thumb when thinking appears.
Days at mansion begin quietly. Before dawn she swings stick forms in garden; if ordered carries market loads yet stops at single word of appreciation to ask reason. What obedience in oath means exactly—she hasn't been asked yet; what she'd answer on night asked even she doesn't know.
