And they link New Mars to Killraven. Are there any Killraven stories in any of the Secret Wars tie-ins? I haven't seen any yet.
They also link Valley of the Flame to Devil Dinosaur, even though Valley of the Flame only appeared (as far as I know so far) in Where Monsters Dwell v2. No Devil Dinosaur there.
And none of the links lead to anything Secret Wars related (well, Valley of Doom links to an interview about 1872 and Weirdworld links to an interview about the new Weirdworld, to be fair); they link to ads for TPBs of classic stories that some of these domains are based on/inspired by. Technopolis links to an ad for Armor Wars, Egyptia links to some New Warriors issues, Dystopia links to the David/Perez Future Imperfect mini from the '90s, etc.
Killraven got me thinking; IF New Mars was intended to have a Killraven story... the original Guardians of the Galaxy are from Killraven's future. These versions of the Guardians appear in Korvac Saga. Korvac Saga ended with the two domains eradicated by the Thors. The only appearance I've seen of New Mars so far is in INHS:AR, where it's a barren wasteland controlled by the Warzone domain. I wonder if the barren wasteland of New Mars was originally the Forest Hills & Holy Wood domains before they were eradicated, and now it's the New Mars wasteland?
Not that any of it really matters, and I'm not actually suggesting anything here. It's all a string of thought based on a mistaken Killraven link on an ad disguised as a map.

Weirdworld #1-5 happens off to the side, doesn’t involve any characters from other domains, but the end overlaps with SECWARS 9. Also, the last few pages happen after the Multiverse is restored.
Red Skull #1-3 has Doom, Strange (both in recent flashbacks), the shield and Abigail Brand. So at least before SECWARS 3-5 (because of Strange), and probably sometime before SECWARS 2. Happens in Killville and the deadlands.
Speaking of Killville, Dr. Strange appears in M.O.D.O.K. Assassin #1-5, as do some of the House of M characters (Magneto, Quicksilver, Scarlet Witch, Polaris & Gambit, who dies) and some Thors (Beta Ray Bill & Angela). Also, Sentinels from the Sentinel Territory (from Years of Future Past). 2099 is seen, but no characters.
This has to happen before Guardians of Knowhere, because this Angela dies there. Also, at least before SECWARS 3-5 because of Strange. Also, before HOM2 1-4 because Quicksilver is still with Magneto here. Years of future Past...
Years of Future Past #1-5 feature the classic purple Sentinels, then introduce Sentinels that look like Doctor Doom (green & grey). The Sentinels that appear in M.O.D.O.K. Assassin are the classic purple ones. I'm pretty sure I've seen Sentinels from this domain in other books, and they've been the classic purple ones. Years of Future Past ends on a cliffhanger, so we don't really know if the Doom Sentinels are the new standard, or if they went back to using the classic Sentinels. There's no crossover of characters from this book into other books (beyond generic Sentinel robots), so I'm not sure it matters too much.
