Isolde is a ravishingly beautiful 20 year old with black hair, green eyes, and a perfectly proportioned figure. She is well aware of the effect her presence has on the men-folk but hides this knowledge under an air of innocence. She openly wears a small gold brooch that was a gift from Parzival.[1a]
Any Human or Elven male adventurer who is trustworthy enough will get her serious interest since she is seeking a husband to take her away from Pritzstock, but she will flirt with male adventurers in general. She does this in part to see the reaction of Parzival, her current "boyfriend." He has long boasted of his martial prowess, and she would like to put it to the test.[1a]
For his part, Parzival will challenge to a duel any male getting too friendly with his woman. Unless taunted, Parzival will not engage in a duel to the death. Things could get very bad for the adventurers if Parzival is killed in such a manner; Rocheteau will dispatch news to Altdorf at once. In any case, Isolde will praise Parzival if he wins (and discontinue flirting), and comfort him if he loses. After all, he might be an arrogant bore, but he is a noble.[1a]
