The Spirits of the Dalish quest is available once you venture back to Arlathan Forest in Dragon Age: The Veilguard. You'll have to recruit Lucanis and venture to Docktown with Neve, but once you've done that, you can get the Unfamiliar Sense quest from Harding and the Winding Ways quest that sees you finding a route back to the forest through the crossroads.
Once back in Arlathan, you'll discover a restless spirit on a boat near to where you ventured to the blighted settlement earlier in the game. This quest involves finding five mementos, but it can be a little confusing knowing what to do after you've gathered them. Here I'll run you through each step of the Spirits of the Dalish quest.
