For my own edification, I've been making a list of variant cards and their status as to existence in the main Sentinels universe or another Sentinels universe. I thought I'd share.
The terms I'm using: Sentinels-Prime (the main universe), Sentinels-Iron (the Iron Legacy universe), Sentinels-XTREME! (the universe of the XTREME Sentinels), Sentinels-Wasteland (the universe represented by the Wasteland), Sentinels-Two (the universe where Baron Blade kills Paul Parsons and Pauline becomes Legacy), Kingkiller (the universe of Kvothe the Six String), Sentinels-Mirror (the universe with a heroic Baron Blade/Luminary and an evil Legacy), Sentinels-Revo (universe where Benchmark is a real hero and Revo-Corp are good guys), and Sentinels-Puzzler (the universe America's Cleverest Legacy comes from).
Not listed, because no promo comes from them yet, are Sentinels-Cocoon (the universe Visionary comes from), Sentinels-Soviet (the universe ColdWar comes from), or the universes represented on the cover of Darkwatch #18.

So, that's at least 11 known universes in the Sentinels multiverse. Most variants are from Sentinels-Prime but quite a few are from the 10 other universes. Questin marks indicate I'm not sure if those characters belong to the Prime universe or not.
The main universe (from our viewpoint). The home of the Freedom Five, Dark Watch, Prime Wardens, Southwest Sentinels, and many others. The primary setting of Sentinels of the Multiverse.

Action Hero Stuntman: Possibly from Sentinels-Mirror.
Young Legacy is from the Prime Timeline. She did a little heroeing before officially doing anything. After all, she could have been at the fight against Blade in Wagner Base if not for her fighting Iron Legacy
No reason not to assume that the various Guise's aren't from Sentinels-Prime, he's a shapeshifter and he was shown fighting the Grocer who was trying to destroy christmas.
Strictly speaking, shouldn't Visionary be listed as Sentinels-Cocoon? For that matter, I think Dark Visionary belongs under "Unknown," since she's apparently from a different alternate timeline, as yet undisclosed. She might or might not be the Vanessa Long of that timeline - I had always assumed she was, but it was recently pointed out to me that this has never been unambigiously stated.
@djwewassson: Gotcha. That puts Action Hero Stuntman as from another universe. Possibly Sentinels-Mirror. We don't have enough clues yet to place him specifically.
With Best of Times Chrono Ranger, we have no reason to believe him to be a different man than the original Chrono Ranger, so though his story starts outside time he is still from Sentienels-Prime by way of Sentinels-Wasteland.
@chaosmancer: That gets complicated. As I understand it, the Mars mission against Baron Blade was supposed to result in two different timelines: one where Paul Parsons dies and his daughter becomes Legacy and one where Pauline dies and her father becomes Iron Legacy. Thanks to the events of Shattered Timelines, neither happened. That, in my opinion, puts America's Newest Legacy in an alternative universe. I've named it Sentinels-Two but acknowledge Sentinels-Two and Sentinels-Cocoon could be the same dimension. Visionary has said Paul Parsons is nothing like her Legacy, after all.
As for Guise, I was mostly kidding. After all, we all know Guise is really the other dimensional duplicate of Pinkie Pie from My Little Pony: Friendship is Magic.
@Ironic: Yes. Visionary would come from Sentinels-Cocoon (which may also be Sentinels-Two, see above) but I was only listing variants. Dark Visionary is, as far as I understand, the same Visionary possessed by an alien entity of some sort. So, she'd also be Earth-Cocoon.
@Belle Sorciere: I believe Dark Visionary to be the original Visionary, just possessed by an entity from outside time and space (aka Jean Grey) since she is freed of that being during the OblivAEON storyline... And that being possibly becomes the "aid aeon".
Less than a year after using her considerable psychic abilities to wrench herself backwards through time, Vanessa Long could feel the impact of her actions. She constantly ached, fought against daily migraines, and her mind was scattered - focusing on this time and reality grew more difficult with each passing day. Worst of all, the dark version of herself which had "hitched a ride" on her jaunt through time fed off her pain.
Anyway, I think the timeline between Visionary's disappearance and reappearance is a bit short to really fit for the "scion's aid" character.
Visionary could not be from a timeline represented on Newest Legacy, because Legacy was alive (and male, almost certainly Paul Parsons) in Visionary's timeline.
I always thought Young Legacy was from the main timeline/universe : when daddy is needed but not available, she takes his place. This is a family business, after all :D
I don't think that's what Scion's Aid is about, either - but it's hard to argue that the timeline is too short, when that Scion was explicitly found outside space and time.
