Coal Construct
The coal construct is older than the powered frames that replaced it and still stands in the halls it was built for, because newer frames fail when the power is out. It burns whatever is shoveled into it and runs about eighteen hours on a full grate. After twelve hours without fuel it takes combustible material from any creature carrying it.
