Darth Alora

Darth Alora was a female Echani Sith Lord who was active during the Clone Wars. She covertly aided the Jedi in their hunt for Darth Sidious, and notoriously raided the Jedi Temple, stealing copies of 80% of the Jedi Archives and unknowingly preserving them beyond the rise of the Empire.

Darth Alora was killed by Darth Vader shortly after the destruction of the Death Star.
