Isn't that just target centurion in someone's home? Anyway if not include the name in the description and where you found it to get any proper answer.

here

According to game lore, you can find such steam centurions in Arkngthunch-Sturdumz dwemer ruin in Vvardenfell, they created when dwemer specters posses carcass of broken steam centurions.
Chroma-Blue Dwarven Spider vamidiums are those powered by gems that emit a cold blue light, said to reflect the frigid stolen soul of the Dwemer engineer trapped within it.
So its pretty much possible to say ghost trapped in centurion.
