Austasia Ir'Wynarn is the adolescent daughter of Prince Aurad ir'Wynarn and his wife Wrenya. She is also the niece of Queen Aurala, and thus part of the Aundairian Royal Family. She has four siblings.
Dreaming of becoming a great explorer, and encouraged by her rascally cousin Princess Corrine, Austasia runs away to pursue her dreams. She leaves Fairhold, possibly with Corrine, disguises herself and attempts to travel to Sharn. Austasia shows promise and may be hero material one day, but she's still too young and isn't ready. It's up to the pc's to recover her before a foreign power or disreputable organization "acquires her" as a pawn to be used against her aunt. Nevertheless if they aren't careful, they could be implicated in her kidnapping.
