Marguerite is the matriarch of the Arnaud family, and the true power behind the trading/smuggling/criminal enterprise that keeps all of her children, grand-children, nephews, nieces, cousins, etc., busy and wealthy. This includes her grandsons Crevan and Cassick.
Marguerite is in her mid-seventies. She is not quite so frail as she seems, nor has her mind dimmed at all, despite her seemingly increasing senility.
