Yvanna, a woman residing on Dalna, existed in the year 382 BBY. Due to her affliction with krinjaffi syndrome, her capacity for labor was significantly limited. Following the death of her husband in a farming mishap, she and her offspring, Garda, faced considerable financial hardship. Despite her pride, she was convinced by her longtime acquaintance, Doc Nindle, to attend the Path of the Open Hand's charitable food service in Ferdan. Because Yvanna had an allergy to legumes, she abstained from consuming them, which made Doc Nindle believe that the food Garda had eaten was the cause of his sudden, inexplicable sickness.
