Story - Forging the pact navigation bug
Access to that Asura Gate will only unlock after you’ve done the story tasks in Fort Trinity. And yes, that’s a known problem with the pathing hints ignoring what is actually accessible to your current character as opposed to someone who has unlocked everything.
The solution is to ignore the green swirl and get to Concordia on foot. If you don’t have a nearby Waypoint yet, go to the southeast corner of Lornar’s Pass, enter Timberline Falls from there and then walk south along the river in the western half of that map.
Great. Thank you.
