He is a Ruthless Seven Servant, and you must defeat him in order to proceed through The Inquisition Quest. Despite his might, the demon known as Zugurosh is a coward, and he would be the first to admit that - if he were threatened enough. Zugurosh spent a good part of his past hiding from real and assumed enemies. Seeking for protection, he joined the ranks of The Ruthless Seven soon after they had established themselves as the mightiest of all surviving cabals. Though he is quick on the uptake, his cowardice prevented him from gaining any significant power until his paranoia helped him to discover a treachery in the ranks of The Ruthless Seven Minions. This granted him the attention of his dark masters and a rather high position in their ranks that only resulted in intensifying his fears.
