Sienna

"Sienna" is the main alias used by a notable Precursor in the late Precursor Empire. A politician in the making, turned warrior, Sienna played a pivotal role in the last days of the Precursor Empire. She fought for justice and oppressed peoples throughout the Galaxy. She was one of "The Four", a group of Artificial Precursors created towards the end of the Precursor Empire.
She held one half of Convergence, one of the Twelve Continuance, which she recieved from her "father" Vysagoth. She eventually passed on her half to her half Titan daughter, Kiara.
