Keter Sephiroth
In dnethack, the Keystone Kops have been removed and replaced with the Keter Sephiroth (Crown Enumerations, singular: Keter Sephirah, plural: Keter Sephiroth). The Keter are based on the Inevitables from 3rd edition D&D.
The naming system used for the Keter Sephiroth is based on the Kabbalah, but the symbolism of the Kabbalah otherwise has nothing to do with the Keter.
malkuth sephirah
The justice enumerations take over the main functionality of the Keystone Kops in dnethack: they are created in large numbers and attempt to block the character off from the stairs, trapping them on the current level. The malkuth sephiroth are significantly more dangerous than the Kops, however, as they are very fast (speed 24), can destroy wands and rings with their electrical attacks, and grab the character, making it difficult to run away or engage in melee combat.
Malkuth sephiroth are the backbone of the forces of the keter. They are never created alone, instead, squads of malkuth accompany one or two of the higher Keter on their missions.
