The Sun Shall Fall

Head to the Palace of the Sun once more and talk to Avad to trigger a scene. After talking to Dervahl. Head to the warehouse beside the Hunter’s Lodge and approach it for another scene.

Inside the unnamed warehouse, examine the first bomb in the ground floor then go upstairs. Check the wooden bracket by the window and examine it to push the bomb off.

Outside the warehouse, use the Focus again to find the trail. Highlight it and keep following it until it leads you to house. Go downstairs to the basement of the house to find a broken wall. Exit through that wall and follow the path until you find Dervahl and his men crossing the walkway underneath the bridge connecting to the palace.

Next, find the climb holds on the side of the cliff nearby then carefully drop down to find more holds and wooden beams. Make your way to the wooden beam then cross the tree wooden rods until you reach the ladder hanging from the side of the walkway. Finally, zipline to the other side and kill the two mercenary lookouts.

Take the stairs to reach the Solarium and trigger another scene. Once in control, interact with the sonic device to destroy it. Follow Dervahl and engage them in battle. Like before, use your blast sling to take out Dervahl and his men with ease.

After defeating the last of his men a cutscene will trigger with the cowering Dervahl activating a lure that summons several glinthawks. Switch to your fire arrows and use them to bring down the glinthawks to the ground, allowing you to follow up with a critical strike or several spear combos. Dervahl will summon more glinthawks so continue what you’re doing until every last one of them has been taken care of.

The objective will then switch to talking to Dervahl. Before doing so, make sure to loot the glinthawk carcasses since they’ll be cleaned up after the story cutscene. When ready, talk to Dervahl to continue with the quest.

After the scene, you just need to talk to Avad and Erend to finish the quest. However, as an optional task, you can talk to Dervahl in his cell and gloat at him. He’ll have a different dialogue every time you attempt to talk to him until he runs out of insults and decides to be silent instead.

Head back to the palace and talk to Erend and Avad to complete the quest.
