Forum:Is the Doctor in Sympathy of the Devil of mainstream continuity because he appeared in The 100 Days of The Doctor?

I hope that my question can be understood from the title. The Doctor (Sympathy for the Devil) is a page with the Nondwu tag on it, and for a very solid reason; he was introduced in a piece not meant to be cannon. But he appeared briefly in The 100 Days of the Doctor (audio story) when the Doctor and Evelyn "side step" into his universe, so should he be considered mainstream because of that? Keep in mind that this is different from Forum:Is The Curse of Fatal Death canon? because that was covering a very vague reference to the alternate Ninth Doctor, while this story is an obvious appearance.

And if he is "in-universe" or however tou want to say it, does that mean that his original two stories are as well? OS25 (talk to me, baby.) 05:25, November 24, 2012 (UTC)


 * Perhaps.
 * That the Doctor side steps / crosses over to another universe, based on our other sources would make it valid.
 * Looking at other sources for instance; TV: Inferno and Battlefield, PROSE: Blood Heat, The Shadows of Avalon and the alternate universe arc of The Infinity Race to The Last Resort all feature alternate universes / parallel timelines which we treat as valid.
 * If he is valid, then his stories would be in-universe, but not of the main universe. In other words yes The Warner Doctor did go to Skaro with the Brigadier but it wasn't the same Skaro or even the same universe in which Hartnell's Doctor went to and McCoy's Doctor blew up. So we'd just treat everything of "Sympathy for the Devil" universe as we do with the Parallel universe (Inferno).
 * The difference here that others may point out is that the Sympathy universe was intended to be non-canon (a term we've by now established doesn't really exist) or to be a "what if" scenario (which Big Finish uses). Our own Doctor Who Unbound article uses the term "premises fundamentally altered" linking to parallel universe. Forum:References to BFDWU as alternate or diverging timeline also discusses this separation and CzechOut stated in that discussion "they're meant to be outside the DWU. That's why they're called unbound — as in "not bound by continuity"."
 * But now brining in this extra reference of the Doctor going there, that means it is a place that can be visited by the Doctor and it, by its reference in 100 Days makes it linked to the main DWU. --Tangerineduel / talk 08:16, November 24, 2012 (UTC)
