Cassandra Thann

Cassandra Thann was the daughter of Zelphar Arunsun and the mother of Danilo Thann.

History
Zelphar came to Waterdeep with a young daughter in tow and eventually met and married Lhestyn.

Personality
Cassandra was a powerful and intellectual matriarch of the Thann clan who almost single-handedly built family's fortunes.

Family
The matriarch had nine children - Dertek, Eldaun, Randor, Zelphar, Harmon, Ildaera, Synthea, Danilo, and Judith - and thirteen grandchildren. Khelben "Ravencloak" Arunsun is her younger brother.

Discrepancy
In the City of Splendors (boxed set), Cassanda is stated as being a 0th level fighter, but later in City of Splendors: Waterdeep, she is a 12th level aristocrat.
