While in the Graveyard of the Fallen, you are tasked with going up to piked heads and accomplishing fights against ghosts of previous foes and skeletons. Once you have gone and completed every task at every head, instead of going to the portal, backtrack to the first burning piked head near the beginning of the stage. You will now be able to interact with it. Doing so will take you to a small area. Move Aarbron in the direction he's facing to see a special cinematic. It is suggested that you have purchased and activate the Planian translation for full enjoyment.
