Besides Books of Sorrow, Greed of Xivu Arath, and three Daughters of Xivu Arath we encounter....not much really. She took off to probably gain more power in the far reaches of the galaxy for awhile....before either working with Savathun willingly or unwillingly. I've been banking on she's in disguise as Umun Arath, The Cabal Primus of Primus'. Reaching deep sure just based off name, but for her to secretly be using a war based race to fuel her war appetite would be brilliant. Going based off just wording...she doesn't need just Hive to cause war. War in itself of any kind will satisfy her worm. . Weirdly enough I could also see her eventually offing Savathun or turning on Savathun. Personally I'd like to se Xivu trick Savathun. Which would be a good FU to her.

Currently? Well Xivu wrath is the youngest osmium sister, and is the hive goddess of war. Was killed by oryx and then brought back from her final death (watch out for that btw). She then buggered of to some corner of the galaxy to go murder things in the name of the sword logic. At some point she started helping Savathûn with the murder battery that is otherwise known as the dreaming city. I do hope that’s all correct, do correct me if it’s not.

Shes a fancy chik

Goddess of war Loved her brother very much Has a hammer for a weapon (remains to be seen) Currently aiding savathune in taking over the dreaming city (however we don't know how involved she is with the fight) Fallows the sword logic much more religiously then her sister And is probably a tomboy if I had to guess
