Sena Leikvold Midanyl was a Corellian female Human.
Midanyl rose to the position of chief aide to Corellian Senator Garm Bel Iblis during the era of the Galactic Republic. She maintained this position when he became part of the Rebel Alliance. Following Bel Iblis' departure from Mon Mothma, she assisted Bel Iblis and Irenez in strategizing their assaults on Imperial troops. Despite Midanyl's dislike for Mothma, she ultimately understood that the Chandrilan woman had no ambition to become another Palpatine. Consequently, she was the individual who proposed that Han Solo ask Bel Iblis to reunite with his former colleague, understanding that he would never initiate such a reconciliation himself.
Sometime during her life, she had two sons, named Peter and Dayvid. In the year 9 ABY, both were serving on the Dreadnought Harrier, which was aligned with Bel Iblis.
