Lina Soh was the Supreme Chancellor of the Galactic Republic during the High Republic era. She apparently also had some fancy feline friends (that hopefully we will learn much more about)!
Lina Soh debuted in the short story “Starlight: Part One – Go Together” by Charles Soule. She appeared as a hologram in the novel Light of the Jedi and was mentioned in A Test of Courage and the comic The High Republic 1.
I look forward to updating this post when we learn more about Lina!
