Once you have the mission you zone into the instance at the same portal to uninstancd Thallassius. You will find Xao Aulin in the temple in the far south area of the zone. You enter the caves and can go left or right, both directions circling around to meet at the temple. Use the lifts to reach the top level and then clear out the room and all roamers. Once agro'd a timer starts, and every 60 seconds four adds spawn. The don't hit that hard, but it does add up. The Regrua (crab) models are not mezzable. Kill him as fast as possible while locking down the adds. It is strongly suggested you bring a chanter for this one. Once Xao is dead the adds do not despawn so be prepared to either gate, evac, or kill them all. Afterwards all that remains is to hail Venloe for the win.

If you are coming from the west, follow the blue line to first lift, the green line to second lift, then red line to Xao. If you are entering from the east, you will be on the proper level already.
