There's no question as to the timeline. With the exception of The Truth, every other comic that discusses Steve Rogers becoming Captain America establishes it as happening prior to Pearl Harbor. His real world first appearance was in a comic published in March 1941, and the reason given for Steve trying to enlist thus wasn't because of Japan's attack on the USA (which hadn't happened yet), but because he was so outraged at what Hitler was doing in Europe; just because America hadn't entered the war didn't mean that people in both the real world and the comic weren't already feeling Hitler needed to be stopped. Captain America Comics #1 establishes Steve's empowering as happening well prior to Pearl Harbor; Giant Size Invaders #1 and the subsequent Invaders series have him already a well established hero by the time of Pearl Harbor; Giant Size Invaders #2, published after the release of The Truth, reconfirms this timeline, as does The Marvels Project. So every comic bar The Truth sticks to this timeline. And even in The Truth, we've got the appearance of a comic that predates the Camp Cathcart soldiers getting experimented on; the Sergeant dismisses it as propaganda, saying the powers that be would go out and find someone to fit the story told within and rename them Steve Rogers to fit the comic, but his supposition is proven wrong because we know Steve Rogers isn't a pseudonym from countless other comics. The Truth's two creators are both on record as noting that Isaiah came after Steve (their quotes can be seen on Isaiah's Wikipedia page http://en.wikipedia.org/wiki/Isaiah_Bradley, and while Wikipedia is often unreliable, it cites the original sources which can easily be checked for veracity). Relevant Marvel Handbook entries have all confirmed this timeline too - Isaiah Bradley's entry notes he was a victim of an attempt to REcreate the formula ALREADY used to empower Steve Rogers, Patriot's entry says likewise, the World War II entry in Blockbusters of the Marvel Universe book also places Steve first, though entries for the Invaders, Master Man, Namor, Human Torch, etc don't mention Isaiah (since they never met him) they all state Steve was already Cap before Pearl Harbor, and this post here http://www.comixfan.net/forums/showpost.php?p=1492315&postcount=1 confirms that these were not errors or oversights on the handbook's part, but that it follows a ruling from Marvel's senior editorial team as to the timeline and who came first. Marvel's official stance is clear - Steve came before Isaiah, and Comicvine's entries on Captain America and Isaiah Bradley, which currently state it the other way round, are in error.
Aurora and Northstar are not half fae - that they were once told they were has been discredited long ago as a piece of mischief on Loki's part. Brian is also not half fae - his father might have come from Otherworld, but he was one of the human inhabitants of that realm. Brian's powers were not inherent to begin with - they came from his amulet and sceptre (not mace) until Merlyn transformed his costume, and transferred the modified powers to it. When Brian was slain and Merlyn reconstructed him, the powers were then transferred to Brian himself, and that's when the costume became a focus for storing the energies needed to fuel Brian's powers.
Sorry kimeraevet, but you've got your timeline utterly wrong. Steve applied to join the army before the US entered the war. By the time of Pearl Harbor, Steve had already been active as Captain America for months; he and Bucky helped form the Invaders within days after Pearl Harbor, months prior to Isaiah enlisting. There was more than one scientist who used the codename Reinstein, which is why you had Abraham Erskine (the "Reinstein" who experimented on Steve) killed but still had a "Reinstein" (Wilfred Nagel) around to experiment on the Camp Cathcart soldiers. That is Marvel's official stance, not the version you have listed.
