Jasael

Jasael, born Adala Ulisil, previously identified as Darth Jasael and formally addressed as Queen Jasael V, was a Sith Queen of the Kingdom of Siqsa of the Sith Hegemony during the Extant War. Sadistic and manipulative, even by the standards of the Sith, Jasael had become identified by her peers and enemies alike as a "Force purist" of sorts.

After the existence of the Voidborn and Logos came about, following the invasion by the Charon Dominion, Jasael believed that existence of them and Force-sensitives were evolutionary, and that the only way for wielders of the Force to survive and continually exist was through the eradication of all that could touch the Void. While Jasael acknowledged the usefulness of the Logos in the war efforts against the Charon, it was later revealed that she ultimately included them in her plan to purge the Void from the galaxy.

A Sith Lady of significant influence, authority and ambition, Jasael found an ally in the Sith King Sycarion IV, who together sought to turn on the Logos after the crisis with the Charon Dominion.
