A former baroness from the house of devils. She wanders the solar system causing havoc for anyone she comes across. Strangely enough however, she leaves a portion of spoils near the last city for humanity to find. Sivris has been around for many years, born just before and fighting in the battle of the twilight gap. She was well known among her kind as a clever and vicious fighter, but he faults lie in her desire for honor and fairness in a battle, often letting her enemies gain an even ground before tearing them down. She climbed the ranks of the house of devils until she achieved the rank of baroness only to have her crew and her title ripped from her during the red war.
When the call came through that several of the houses were coming together to fight both humanity and the cabal, Sivris was both wary and pleased at the prospect of a stronger fighting force. However on her flight from old Russia to join the house of dusk her skiff was shot down by cabal forces, leaving her crew dead, and Sivris herself trapped and injured in the wreckage. Eventually, a lone guardian, weakened by the loss of his light came across the fallen baroness, and freed her from the wreckage. The two agreed that in order to survive the cabals onslaught on earth the two of them had to set aside their differences and distrust of one another and work together.
Over the course several months, the two had grown to respect one another, the warlock himself even taking it upon himself to modify a broken servitor in order to provide Sivris with a more efficient source of ether. So when the human was killed in an ambush, Sivris was enraged and distraught, and vowed to rain fury on those who dared to even threaten humanity. And although she has never directly come in contact with any other guardians, rumors began to emerge or her endeavors.
A fallen baroness, marked in the colors of the house of devils, who would destroy waves of vex single handedly, break the blades of hive knights as if they were made of paper, fight cabal centurions bare handed, and would even force her own kind into submission should any of them be caught harming the lives of those who lived in the last city. A fallen truly worthy of the title of devil baroness.
