[She tries to parse this down to the briefest summary possible.]
Soooo you have an evil uncle, Unalaq, only no one knew he was evil because he was really good at purifying spirits and there were a lot of angry spirits around. You learned that Harmonic Convergence--that's when Raava the light spirit and Vaatu the dark spirit fight to see which one will dominate the next ten thousand years--is about to happen and you had to find Dad so he could guide you in the spirit world.
Dad was upset because he couldn't get to the spirit world, but then Aunt Kya made me tell him that maybe I could, so we went to the spirit world together. We got separated and I found Wan Shi Tong's library, which is the most amazing place ever, and learned that Vaatu could be released--did I mention he was imprisoned in a tree by the first Avatar?--if the Northern and Southern spirit portals were both open when Harmonic Convergence happened. But then Wan Shi Tong was working with your evil uncle who stole me and threatened to take my soul if you didn't open the Northern spirit portal. You opened the portal--which was kind of dumb--and I got stuck in the spirit world until Dad and Aunt Kya and Uncle Bumi rescued me.
[She isn't going to pause to dwell on the Fog of Lost Souls or how close she came to dying, thanks.]
By then, Harmonic Convergence had happened and Vaatu was free and Unalaq combined with Vaatu. That made him the opposite of the Avatar, who's bound to Raava. You two fought in the spirit world and your evil uncle destroyed Raava and broke the Avatar cycle. When Dad found me, I knew that you needed help so my spirit went to Republic City where all of your spiritual energy was fighting Unalaq and Vaatu, and I showed you that Vaatu can't exist without Raava and you pulled Raava out of Vaatu and Unalaq died. You and Raava got to bond again, so you're still the Avatar, but you lost your connection to all of the other Avatars. After that, you decided to leave the spirit portals open because you thought that spirits and people should live together without the Avatar bridging the worlds.
[She stops. Did she cover everything? No, not really, but that was most of it.]
Oh! And the projection of your spiritual energy looks like a giant blue you with glowing eyes, if you wanted to know.
