Celerity Demons are powerful upper-level demons who feed off lesser demons. They are described as a proud and aggressive species that prefer to live in solitude. Because Celerity Demons can move faster than human sight, are very difficult to find and fight. However, they can be vanquished through a potion. They can also be vanquished through powerful magical powers like Molecular Combustion, as shown when Piper vanquished Sarpedon.
