So the first thing you have to do is start Vimana Agama – Ararycan World Quest to show the location of the hidden teleport waypoint.
Now you have to teleport to the Devantaka Mountain statue of the seven and head towards the northeast and there you have to talk to Ararycan.
Once you find Ararycan you have to finish her dialogue and then turn around and investigate the strange spot.
