Unidentified female Twi'lek Jedi

A female Twi'lek Jedi engaged in a lightsaber duel with Dark Lord of the Sith Exar Kun sometime before the death of his physical form in 3,996 BBY. She was killed by Kun and their duel was depicted in a fresco sometime later. The fresco was discovered in the catacombs beneath the Temple of Exar Kun on the moon Yavin 4 by a group of spacers during the Galactic Civil War.
