Each one of the Ruthless Seven represents a hell circle. Each one bears a kind of disfortune that might happen. Fire, despair, plague, damnation, destruction, deceit and undeath.
Within the Tibian history, the Ruthless Seven learned the forgotten art of dreamwalking and dominated all the pivotal points of meeting for the Nightmare Knights, thus cutting them off from each other. That has almost annihilated the ancient knightly order. Before they were wiped out, they created a maze underneath the Plains of Havoc, inside the very inferno pits, where they had built an outpost. In this maze, there is a throne room for each one of the Ruthless Seven, each one having a small essence of these wicked demons.
