Sword of The Flames | Karma
The sword that can create fire was stolen from one of the 7 angels, forged from the fires of stars long passed before Nero himself was awake. A half of a star, with the other half asleep in the garden.
It listens but never talks. Due to it being residing in the Aether it most likely never is aware that it's alive. It does think sometimes, mostly concerned over it's wielder.
It never blames itself, it knows it's just a weapon so any of the lives lost wasn't it's fault. It still think about it. However, it also thinks about if it's wielder is also being used as a weapon too.
