Just like Dragon Age: Origins, Dragon Age: The Veilguard is going to have Darkspawn, Archdemons, and Grey Wardens. What it probably is not going to have is The Grey Warden, the protagonist of Dragon Age: Origins. Dragon Age 2 and Dragon Age: Inquisition both excluded The Warden, but the plot of Dragon Age: The Veilguard means players are going to be forced to suspend some serious disbelief to ignore the fact that their favorite character is absurdly missing.
