The Flash Au: The Allen Council

"What if fixing your biggest mistake created a universe you don't even recognize?"
Barry Allen thought he fixed Flashpoint. He thought he restored the timeline, saved his friends, and put his life back together. But when he steps out of the Speed Force, the reality he finds is drastically, astonishingly different.
His mother is alive, but his father was murdered by the Reverse-Flash. Iris West is happily in love with a very-much-alive, steel-skinned Eddie Thawne. And the biggest shock of all? Barry is no longer an only child.
Welcome to the Allen Council.
Barry discovers he has a twin sister, the silver-armored warrior Sara Lance, and triplet younger siblings: Nate, Liam, and Jesse. Together, their DNA is bound to a cosmic force-the Infinity Stones. From alien Omnitrix technology and ancient Chimera curses to boundless Rune Magic, Barry must learn to lead a family of powerhouses while mastering his own new abilities fueled by the Mind Stone and golden lightning.
But with great power comes terrifying threats. As Alchemy manipulates the shadows and the horrifying Speed God, Savitar, declares war on the Council, Barry finds his ultimate anchor in the most unexpected person: Caitlin Snow. Bound by a two-year relationship he barely remembers, Barry falls in love with her all over again, just as Caitlin begins to awaken a dark, chaos-magic-wielding alter-ego known as "Chaotic."
The timeline is a broken cup, and the pieces will never fit perfectly again. But the golden light shining through the cracks might just be exactly what the multiverse needs to survive.
