Matron Mother Malevolence is a shivarra located at the Seat of Command and Illidari Foothold on Mardum.
She is accompanied by Priestesses of Delight, Shivarra Destroyers and Priestesses of Dementias. By her own admission, she joined the Illidari because she considered Sargeras "a bore" and felt that there was no fun in his goal to destroy all life.
- What a rare honor. To be one of the Illidari, instead of a servant. I must admit, I was worried you wouldn't choose me as one of your champions.
- But now you have, and I could just kiss you!
- It never made any sense to me that all worlds should be purged in flame when there are so many delicious playthings to have fun with. Sargeras can be such a bore. Together, we will bring the Burning Legion to its knees and make them grovel in the dirt.
- Well, hello there.
- I'd sooner kill you than look at you, but let's start with look.
- Your wish might be my command. Then again...
- Yes, I am on your side. It's complicated, for reasons.
- I live to serve the Illidari.
- Oh, no you did not!
- Well, this is wholly inappropriate! I'm hardly dressed for a poking war.
- Hey, that one hurt! I don't take pain, I deliver it.
- I'm starting to think that I need to put you over my knee! A six-arm spanking is in order.
- ENOUGH! [Unintelligible Eredun cursing]
- No hug before you go?
- Next time, eyes all the way up here.
- Let's do this again real soon.
- I always love our little chats.
- Try not to forget that the Legion wants to burn all worlds, especially yours.
- A simple task.
- You called?
- Your wish is my command.
- Her title is a likely reference to the Matron Mothers found in Forgotten Realms lore, the powerful leaders of the matriarchal drow.
- During demon hunter's quest  The Arcane Way it is revealed, that she had a liaison with Archmage Lan'dalock somehow.
