Auntie was a humanoid who aided the sentient asteroid House in bringing TARDISes to him.
She was transported via a rift in spacetime to House, where she lived with Uncle, Nephew and Idris.
Auntie was composed mainly of body parts stolen from Time Lords and other creatures which found themselves in the junkyard. Auntie had the Corsair's left forearm and hand at the time of her death, which was recognisable by the Ouroboros tattoo which he had for each regeneration. She referred to the arm as being "a good arm for [her]."
She, Uncle and Nephew were kept alive by House in return for doing House's bidding. When House left the asteroid, Auntie and Uncle were doomed to die, as they both relied on it to remain alive. She and Uncle remained stoic in the face of their deaths. Auntie casually referred to it as "time for Auntie and Uncle to pop off."
“Letting it get to you. You know what that’s called? Being alive. Best thing there is. Being alive right now is all that counts.”

You should always listen to the doctor. That's why @docdust brought Auntie back to life as @anauntie
I once was {@anauntie & @andagon} an enhanced anarchist being, hybrid of a humanoid called Auntie (™TARDIS eating HOUSE) and a warmongering chthonic fish demon called Duke Dagon. But as @andagon realised they wanted to go their way, we had to separate physically.
On separate paths now, but flesh from one flesh.
I AM AnAuntie.
We - Uncle and Auntie - were the abject:
I defy Death! I join the fallen:
I want to live! I want to love.
Say it loud: Humanoid and proud!
