To the casual observer Marthine can come off as remote, inscrutable, and even a little subtly frightening at times.  Once one takes the time to interact with her, they will instead find that she is a chummy and endearing sort... or dismissive and stand-offish.
-"...like my aunt Hallbera.  She's a good person, if you're good to her."
-"She's spooky.  Only talks to you when she wants to, no regard for how you feel on the matter or for what she has to say."
-"Like the cats she keeps in her home... She lives by her terms, and interacts on her terms."

Marthine is shorter than might be expected for a Woman of Lake-town.  Her hair is golden-blonde and frames a lighter-colored, "feral-aspected" face set with green eyes.  She wears a cloak with a hood reminiscent of cat ears, and a long vest with leggings.  She carries a plain staff with herself, and at her hip can be seen a small gun.  The "clink" of chains can be heard as she walks.
