Shareen was a Mist-Weaver of ancient human descent and female identity. She, together with Awglk and Wkk'e, found themselves confined within an exogorth a very long time prior to the New Republic era. To endure their entrapment within the exogorth and decelerate the passage of time, Shareen and her Mist-Weaver companions encased themselves in a protective cocoon. Ultimately, Jedi Luke Skywalker and a female biologist affiliated with the University of Bar'leth came upon the Mist-Weavers in their cocoon. Following an exchange with Luke Skywalker, the Mist-Weavers consented to his freeing them from their encasement by using his lightsaber to break it open. This action resulted in a significant release of energy, which liberated Skywalker and the biologist from the exogorth but resulted in the Mist-Weaver's lives being lost.
