Adventure Guide Entry
The in-game Adventure Guide text for the Corstilax encounter in The Arcway.
This massive construct patrols the tunnels beneath Suramar, searching for anomalies and correcting them. He has detected one such anomaly - a breach in one of the conduits that carries the power of the Nightwell - and works to repair it. But living outsiders wandering the tunnels are also an anomaly; one that Corstilax is empowered to remedy.
