Four Elite Dark Lords

About
The Elite Four Dark Lords are the most powerful and influential Dark Lords on the monster realm, directly beneath the Supreme Dark Lord and the Demon King himself. They tend to be stronger and older than most Dark Lords, although strength is not the only requirement since Dark Lords like RedEye possesses immense power and is not part of the four.

There can only be four at the same time. Whether they are given their status by the Demon King or by other means is unknown.

All four of the elite dark lord possess an individual castle in the monster realm, which are probably inherited after a former elite dark lord dies or steps down from the position. Dark Lords Xavier and Noce both were part of the Four Elite in the past but stepped down for their own reasons.
