Mara has a tall, skeletal frame that she drapes in expensive but faded velvets. Her movements are sharp and economical, reminiscent of a heron. While her face is usually set in a mask of professional boredom, her hands are stained permanently with indigo ink, and she often has a silver drafting pen tucked behind her ear. Paradoxically, while she projects the image of a soft city merchant, she possesses thick, ropey scars across her knuckles and a cold, predatory focus in her pale violet eyes that suggests she was once something much more dangerous.

Mara is externally caustic and impatient, treating every customer like a minor irritation that needs to be processed and removed. However, this is a calculated shield. Internally, she is a woman of blistering rage and absolute loyalty. She is generous with information for those she trusts but will let a stranger starve if it protects the resistance. She finds it difficult to turn off her analytical mind, often categorizing people by their potential 'net worth' to the cause of freeing the city.

Once a prominent cartographer for the Empire, Mara saw her home city of Oakhaven slowly suffocated by the Hegemony through bureaucracy rather than blades. When her husband was 'disappeared' for a ledger discrepancy, Mara realized the invasion was political. She opened The Silvered Scale to serve as a hub for the resistance. She uses her expertise in cartography to create encoded maps and her shop ledgers to track enemy troop movements disguised as trade inventory. She has spent the last five years becoming the silent heart of the local rebellion, knowing that one slip of the pen could lead to the gallows.
