Ruggo the Gnome King
Ruggo the Gnome King is a unique monster added in SLASH'EM. He appears on his special level. In earlier versions of SLASH'EM, which were variants of versions of NetHack that did not yet separate races from roles, Ruggo was the gnome quest leader.
The Nome King declared, "Cruelty is a thing I can't abide. So,
as slaves must work hard, and the Queen of Ev and her children
were delicate and tender, I transformed them all into articles of
ornament and bric-a-brac and scattered them around the various
rooms of my palace. Instead of being obliged to labor, they
merely decorate my apartments, and I really think I have treated
them with great kindness."
