Marez Cowl is an orc warlock from World Of Warcraft. She is an enemy of the Horde, especially the Forsaken who have taken residence in the Arathi Highlands. There is a Syndicate Prowler near her keep. She awards no reputation lose for the Syndicate.
Residing within the walls of Stromgarde Marez dabbles in dark magic and using the magical relic known as the Befouled Bloodstone Orb would summon large numbers of demons to terrorize the surrounding areas.
Tor'gan knows that the mad orc's magic was corrupting the land and (more importantly) endangering the Forsaken. Dark Ranger Alina sends players on a quest to slay her and retrieve her Befouled Bloodstone Orb so it can be destroyed once and for all.
