Mist Fiend

[Mist Fiend devil race is extremely greedy by nature and fond of eating. They love to eat the flesh of formidable beings. The more formidable is the being they devour, the faster they mature and the more powerful they become. Among devil king class monsters, they are an extremely rarely seen powerful race. According to legends, they possess a hint of devil god class life-form's bloodline. But the Mist Fiend race was found to have vanished during humanity's explorations long ago and is considered to have gone extinct.]
