Go to Concordia Waypoint in Gyre Rapids, Timberline Falls. From there interact with the story star to start the instance. After some dialogue head towards the fort, where you'll find some Mordrem. Make sure to revive any fallen allies, as they will help you with the mobs. When the fort is clear there'll be some more dialogue; speak with Tactician Art to decide who to take with you to find Magister Lindsay. Track Lindsay's trail by heading northwest, to the area marked with a green circle on the map - the Magister and two other NPCs can be found in a small cave there, trapped by a few Mordrem. After rescuing Lindsay, escort her and the caravan to Goldenlight Hallow lab. Unfortunately, the lab is under attack, so secure the area around it. Finally, discuss the situation with Rox.
