Remnants of fire refer to the residual materials and evidence left behind after a fire has burned through a particular area. This can include ash, charred debris, burnt structures, and any remaining unburned materials. These remnants can provide insights into the intensity and duration of the fire, as well as its effects on the environment and surrounding structures. They can also be important for forensic investigations to determine the cause of the fire.
The remnants of fire are typically referred to as ashes or embers. Ashes consist of the residue from burned materials, while embers are the hot, glowing remains of a fire that can reignite if not properly extinguished.

I believe you mean remnants. A remanant is something that remains. It can typically refer to a thing (after the fire, only remnants of the house were left) but can also refer to something intangible like a belief or idea.
