Doña María Teresa (Tessa) Alvarado, born in California and sent by her father, Don Alvarado, to Madrid at the age of seven to further her education. In her early twenties, Tessa has been taking fencing lessons from Maestro Juan Torres (Anthony De Longis), when she learns of her father's death and returns to California to take over her father's hacienda. The Queen is never depicted as physically stronger than her opponents, winning by being more skilled or using the element of surprise and when the odds are too great, running away to fight another day.
