WARNING: Major spoilers ahead for Dragon Age: Origins and the novel Dragon Age: Asunder ahead. Proceed at your own risk.
Fans have spent a lot of time speculating about the story of the upcoming Dragon Age: Dreadwolf. Dragon Age: Inquisition players will more or less know what the titular characters' goals and motivations are, but there's quite a lot that remains mysterious. Meanwhile, fans have poured over the previous games, comics and tie-in novels, and recent animated series for clues about what to expect in Dragon Age: Dreadwolf.
This speculation extends to Dreadwolf's characters. BioWare has confirmed that a few familiar faces will make a comeback, with fans speculating who else might make an appearance in the new Dragon Age game, like if Merrill returns in Dragon Age: Dreadwolf. And while it would take a bit of effort to make it work, Dragon Age: Dreadwolf has an opportunity to bring back the mother-and-son pair of Wynne and Rhys.
Dragon Age's Wynne and Rhys
Fans of the Dragon Age novels, or anyone who's spent enough time poking around the fan wiki, might raise an eyebrow at the idea of Wynne returning in Dragon Age: Dreadwolf. Players meet Wynne from Ferelden's Circle of Magi in Dragon Age: Origins, while she is a Senior Enchanter. Wynne had a particular affinity for spirit since a young age, befriending a Spirit of Faith while visiting the Fade in her dreams. This spirit effectively became her guardian angel, protecting her from demons. When Wynne falls in battle during Dragon Age: Origins, the spirit's attempt to save her inadvertently results in the spirit possessing her, though she retains control over her mind and body.
As a young woman, Wynne had an affair with a Templar and gave birth to a son named Rhys. The Circle separated them at birth, and Wynne and Rhys would not meet again until many years later, and the two were not particularly close. However, that didn't prevent them from working together during the events of the novel Dragon Age: Asunder, which bridges the gap between the main events of Dragon Age 2 and Dragon Age: Inquisition. Unfortunately, Rhys' and Wynne's reunion was not meant to last, as she sacrificed her life to save the Templar Knight-Captain Evangeline.
How Wynne and Rhys Could Return in Dragon Age: Dreadwolf
Wynne's death prior to the events of Dragon Age: Inquisition is a big strike against the likelihood of her appearing in Dragon Age: Dreadwolf. However, it's not necessarily the deal-breaker that people might assume.
Dragon Age has always been unclear about what happens after someone in its world dies. A few scenes in some of the games and books can be interpreted as someone's soul still existing in the Fade after they die. However, the series also shows how spirits and demons can take the forms of mortals, including those who are already dead. Anders and Justice in Dragon Age 2 also demonstrate how when a human and a spirit share a body for long enough, it can be hard to tell where one ends and the other begins.
This is where it's worth noting that Wynne's spirit of faith is still around, co-existing within the body of the former Knight-Captain Evangeline. And considering how vital a role the Fade is likely to play in the plot of Dragon Age: Dreadwolf, it's almost certain that players will spend at least some time visiting the realm of spirits. If so, this could be an excellent opportunity for the mother-and-son duo to have an unexpected reunion.
There would likely be some lingering ambiguity about whether this version of Wynne is real. The nature of Dragon Age's Fade also begs questions about what "real" even means in that context. However, that's not necessarily a problem and could have some very interesting implications. This would also allow Wynne to have a proper in-game send-off rather than dying in a novel that not every Dragon Age fan has read.
Dragon Age: Dreadwolf is in development.
