Map location of Rustmaul Dig Site.
Rustmaul Dig Site is an abandoned dwarven digsite in the Shimmering Flats. Some dwarves that were digging here were driven off by a raid of Horde hunters and warriors lead by Moktar Krin. Much to the raid's dismay, silithid began pouring out of one of their hives. Some killed and some injured, they fled to Horde territory. Korran was one of them. Now the aggressive silithid wander around the abandoned dig.
One noteworthy silithid is Silithid Ravager
The interior of the silithid hive itself.
