The Eluvian will give us fast travel

Dragon Age: The Veilguard isn’t using the same open-zone structure as Inquisition, but it will let you explore multiple regions of the Dragon Age universe. This is through the elven Eluvian network. Its mirrors act as portals that connect different areas of the world, and this is how Rook and friends will go to different locations with ease. We can see Rook and their team passing through the network and entering a whole new space. Seems like a good way for Veilguard’s story and action to have you crossing large distances and incorporating more of the world.
