Medium-sized and presentable, Indigo is named for her black hair with its blue-violet sheen and the deep hue of her wide dark eyes. Her age is indeterminate, though the best guess is somewhere in her thirties, and she moves with an economical grace.

She is always clad in loose, comfortable garb of silk and is never without her black silk headband.

The Circle knows that Indigo is a bastard of House Sesus and a skilled alchemist with a profitable sideline in medicine. She likes to live well and has the resources to match. And no one, not even the Circle, has ever seen her anima flare.
