Vivienne is a dark-haired, dark-eyed young woman. While she certainly stays in shape, she doesn't seem to be concerned with athletic pursuits; instead, she concentrates on her mage skills, specializing in summoning magics.

Personality-wise... Vivienne can be a bit of a pain. She is perhaps over-proud of her intellect, and is perfectly willing to talk down to people she doesn't regard as intelligent. She can be abrupt to the point of rudeness when she's busy with something other than the person speaking to her. She can be nice, and polite, and charming - but that's more likely to happen if she wants something from them.

It's not uncommon to encounter Vivienne in Court, but although she's doing her best to be charming, it sometimes seems she's there only reluctantly. Much more of her time is spent at the school for orphans she founded and runs, Vivienne's Academy for Higher Learning. The Academy is situated in the lower city, and is surprisingly picky about the orphans it accepts; she makes regular visits to the orphanages in the city and solicits donations from the nobles of the city.

What's less well-known about the Academy is that Vivienne is so picky because she is the proud runner of Amber's major thieves' guild... which is full of Academy students and Academy graduates. She's working to get her students placed in the highest places she can get them, to make her thieving work that much easier...

Vivienne has one pet, an Abyssinian cat she calls Firestarter. He tends to be by her side, or in her arms, or on her shoulders, whenever possible. It seems likely that the two of them share some personality traits; her comments on where the cat came from have been that he chose to stick around after a summoning.

Firestarter is actually a fire elemental. Given time and fuel, he can transform into a horse - but cat is his preferred form.
