The night before the wedding of Barry Allen and Iris West, the two most unlikely people find kindred souls in each other, and both Oliver Queen and Kara Danvers walk away from the Earth-X crisis for the better.

So when Alex Danvers tumbles out of a breach in Star City without Kara just a few days before the holidays on Earth-1, Oliver and members of Team Flash rush to bring Kara out of her coma. As the Kryptonian recovers, both Oliver and Caitlin volunteer to stay and assist the D.E.O., Oliver as a fielder and Caitlin as a medic and field support only as needed.

But when Oliver and Kara are abducted during a mission and taken by the devil herself, how changed are they when they return? And in the fight against Project Cadmus, can an enemy truly redeem herself?

MAIN CAST

THE JUSTICE LEAGUE

Melissa Benoist as Kara Danvers/Supergirl

"You know, a few days ago, I wouldn't have thought I had even a slim chance of escaping here. Now I'm beginning to believe we can, together."

Stephen Amell as Oliver Queen/Green Arrow

"The island I was stuck on was literally named Purgatory in Mandarin. That place was hell like I've never experienced before, and coming from me, that's saying something."

Odette Annable as Samantha Arias/Reign

"They'll get what's coming for them, Kara. Justice will be served, one way or another."

Katie McGrath as Lena Luthor

"Well, you know what they say . . . hell hath no fury like a woman scorned."

Amy Jackson as Imra Ardeen/Saturn Girl

"To fight alongside the superhero I admire is an honor, yes. It is a greater one that I have to call her my friend."

Danielle Panabaker as Caitlin Snow/Killer Frost

"Either shut him up or knock him out!"

PROJECT CADMUS

Brenda Strong as Lillian Luthor

"I've broken things much tougher than you . . . what did she say your name was? Oliver?"

David Harewood as Hank Henshaw/Cyborg Superman

"An alien refugee made me lose my organization. Another alien, this one a cheerleader, has foiled us time and time again. This time, neither of them are going to be so lucky."

OK . . . I think I've about had it with SuperArrow stories right now. One series and three upcoming books is enough for me right now. XD

Anyways . . . yes, I did just call them the Justice League, Legion of Superheroes was already taken. No, Oliver will not be the only guy in it - this is just the main cast, more will join in.

Yes, Lena is going to find out Kara is Supergirl in this. Yes, this is AU after "Reign," so "Legion of Super-Heroes" never happened. However, this will take place before "Irreconcilable Differences" and, more than likely, before "Don't Run" to accommodate Caitlin.

Yes, Kara and Imra are going to be friends in this. Some people hate Imra - I mean, what did she do wrong? Nothing, except annoy Karamel shippers, apparently. But since this is SuperArrow (yes, I know, you're all shellshocked), that's not a problem . . . unless Oliver decides to punch Mon-El. Or maybe Imra will decide letting Oliver punch him is OK.

Yes, this will be a Reign redemption arc. Because I love Sam, and I say she should have one. Here's my take on it.

And yes, this is another Cadmus is the main enemy story. I just like coming up with different ways to destroy them. Besides, this one will be just a little bit different than my other Cadmus stories, as you can tell by the description and some of the quotes above. ;)

I honest to God don't know how this idea popped into my head, but one thing led to another and . . . well, this is the outcome.

Hope it sounds interesting enough for everyone to put it in their libraries! :D
