The name was changed from Dragon Age: Dreadwolf to The Veilguard to better reflect the game's focus on the companions and their stories, rather than just the antagonist, Solas. The developers felt that the new title represented the heart of the game more accurately.
According to Gary McKay, Solas still plays a significant role in Dragon Age: The Veilguard, despite the title change. He mentions that Solas is not taking a back seat, and that the game's focus on companions complements Solas' narrative, allowing for a broader story about The Veilguard and the world as a whole.
John Epler describes the development process of The Veilguard as an evolving journey, with the team learning and realizing that the game's beating heart lies in its diverse companions5. As they built the game, it became clear that the focus shifted towards the team, and the title "The Veilguard" emerged as a better representation of the game's essence compared to "Dreadwolf," which suggested a focus on an individual character.
