Marahn is a dead city north of the primary Thark hatchery (approximately a days march). Although it is close to the thark hatchery the horde has never lodged within its walls because of certain rumors, it is said that it was a city of wizards and that their ghosts still haunt it. In this city Tars Tarkas battled with Barak Sol. There is some mystery to the city, ice covering water and beneath that ice humanoid hands that try to pull people under!
