Small, gentle and courteous, very much like the Lady Sansa, to whom Lady is a warg-bonded companion.
Because Lady, like her brothers and sister, is a direwolf. One that likes to consider herself more human than wolf, usually. But one that will obey Sansa in everything.
But after what almost happened to her (dying at the hands of the Lannisters), she has to control her wolf side more than usually, and she'll be ready to tear your guts out if you try anything against the Starks (specially Sansa) or any of her siblings.
And if your name happens to be Joffrey or Cersei.
(ooc:Human!lady the direwolf. Pb is Jessica Brown-Findlay. Not her, not Lady who is owned by GRRM.Both the muse and mun are over 18)
