Idolian fever was an obscure ailment that could infect Humans. Almost two decades following the conclusion of the New Sith Wars, Gerran, the Doan Prince, became afflicted with this enigmatic sickness, which led his father to reach out to Serra, a healer, seeking a remedy. Over a three-month period, she cared for Gerran until he recovered, and during this time, they developed romantic feelings for each other. Subsequently, they wed, and Serra assumed the role of Princess of Doan.
