On Ameridan's Trail

Follow the river north from Professor Kenric and look for spires.

Encounter groups of Hakkonites near each spire; you can choose to fight them or bypass them.

After the fourth spire, follow the path up a hill and then north over a bridge.

Continue north to reach the entrance of an ancient ruin, where you will encounter Hakkonites, including a Champion. Spread out to avoid Area of Effect attacks.

After defeating the Hakkonites in the courtyard, interact with the bench near the entrance to wait for Professor Kenric and Scout Harding.

Enter the ruins and approach the floor puzzle. Step on the correct platforms in order to open the way. The lever behind the platforms will reset the puzzle. The correct order is 1, 2, 3, 4, 5.

Loot the chest and examine the Tevinter Carving in the room to the east before proceeding north.

To pass the magical barrier to the north, head east from the barrier along the walls of the ruins to find veilfire.

Pick up the veilfire and take it to the barrier to dispel it.

After a cutscene, pick up a veilfire torch to uncover two runes on the walls within the chamber.

Activate the runes.

Head back along the walls from the wooden planks to the left outside the chamber.

Find and pull a lever at the opposite end of the walls to grant access to trail markers.

Activate the trail markers, starting with the one atop the stairs in front of the chamber.

Follow the map icons and activate each trail marker to complete the quest.
