The Forgotten.

A rouge organization bent on revenge.

Leader: Feru’Tsava

Info:
Feru ‘Tsava was a sangheili native to the planet Toran in the outer rim.

He was planning to wed another sangheili named tara, as they were deeply in love since childhood. Until one fateful day General Grievous and his army assaulted their world for forerunner tech, and nearly wiped out all life on the planet. The Arbiter’s army under the command of Jedi Pong krell attempted to take back the planet. But abandoned the planet after recklessly getting all of his forces killed in a boarding attempt.

In the resulting battle, Tara and Feru’s entire family killed by orbital bombardment.

After the battle, Feru began to grow resentment toward the Arbiter. He believed the Arbiter allowed the Sepratists to destroy their planet and kill his wife to be.

He started gathering followers, particularly the other survivors, and began raising an army to destroy the Arbiter, AND General Grievous.
