The Navis Nobilite representative of House De Wynter comes in the form of young Lady Lucretia, a lithe and strange mutant figure bereft of all hair and with skin as pale as snow. Few see her blue eyes, as she often wears and ostentatious headpiece that covers the top of her head, her eyes, and more importantly, her Navigator's eye, and is shown in the headpiece as a stylised, closed eye set in porcelain. Over his she dons a wispy veil that is a set to her very rich and decorated dress. Her arms and legs are slender, her fingers thin. Puffy lips give her as much an attractive look as she could possibly have with her mutant malignancies against her.

She's often seen wandering with a contingent of various House servants milling nearby and around her, and a decorated, particularly well-liked servoskull that floats nearby wherever she goes. In times of need, she dons a xenomesh armour that accentuates her form, even though she does not particularly comfortable in it. Accompanying this is her personal wargear, which consists of two expensive pistols and a curved sword, a powered blade by the looks of it.

Her demeanour comes off as aloof and aristrocratic, as she well knows her worth to the ship, and her role in guiding the voidships of the Imperium, but even so she knows her place in the Dynasty, and serves her Captain with zealous fervor.
