Yensin Tiralli

Yensin Tiralli was a male human Senator in the Galactic Republic and the father of Darth Amorosa, representing the planet of Dantooine. He was known to be friends with both Darth Mayrik and Mon Mothma, but was unaware of Mayrik's Sith identity. At some point, Tiralli and Mayrik became lovers. Mayrik kept Aliana secret from him due to the potential fallout in his political career upon learning he fathered a Sith Acolyte and future Dark Lady of the Sith.

During the First Order-Republic War, Tiralli became curious about Rey Beniko's surname. This led him to be introduced to Amorosa and learn the truth about her and Mayrik. Though Amorosa rejected him as a father, she agreed to share holofrequencies in case either were needed. Tiralli could tell that Amorosa had been through a harrowing ordeal and didn't judge her for rejecting him, resolving to at least be a friend to her.

After the war, and the subsequent rise of the Sith Empire, Tiralli was one of the most vocal voices for an alliance with the Empire. Though initially a minority, the subsequent election of Chancellor Rose Tico saw his desires bear fruit.

=Trivia=
 * Tiralli was initially planned to be unnamed and never appearing, with Amorosa knowing nothing about him and not caring to know anything about him. This was changed due to initial feedback about the intensely problematic implications of Amorosa having an absent father. Though still not wanting a father in her life, Tiralli shows nothing but compassion and support toward his child.
 * Fan interpretation about Tiralli before his appearance had him portrayed as a goofy father trying to make up for lost time. His actual characterization upon his inclusion in the story was far more relaxed and paternal, going as far as to give Rey a firm but non-judgmental lecture about pressuring her wife into situations she's uncomfortable with.
