The mural at Gjallarhorn has revealed that it is not only Ifrit that Ultima covets for his vessel, but both Ifrit and the Phoenix. Their resolve renewed, the brothers Rosfield begin the final leg of their journey from Eistla to the capital.
Brotherhood begins immediately after you finish The Last King and watch the cutscene.
Head forward, leaving Eistla north through the gate towards the marker. You can pick up a Side Quest named Laid to Rest here, if you want. After a short while, you'll come to another gate — open it and watch the cutscene.
Proceed forward. The area is open for exploration, so feel free to roam around for a bit. When you're ready, head to the marker. You'll be up against several waves of Akashic enemies.
After the fight, proceed through the gate and watch the brief cutscene. The next area is also open to explore, so take a look around and fight a new more enemy groups if you wish.
Make your way towards the marked location. Once you reach it, watch the cutscene. Fast travel to Drake's Spine to end the quest.
