Previously, on Fairy Tail:

Season 1 (Flames of Friendship): (Begins after the Grand Magic Games arc from the anime/manga) While hunting down a dark guild that managed to defeat Erza, Team Natsu had an encounter with a rival guild, White Eclipse. After defeating the lesser members of the dark guild, they encountered a scared, injured little girl. The girl soon passed out after a confrontation with Natsu. After a stores of events, the girl, Cynthia Rose, became the newest member of Fairy Tail. Little did they know, the Council was out to get her. A promise between Cynthia and Wendy ended up with Wendy becoming the Omega Flame Sky dragon not too long after. After that, Wendy and Cynthia went on a job together, only to do battle with the Council's top three captains, Aloy, Odin, and Correll, in attempt to protect Cynthia from them. Little dod they all know that Cynthia's father, Aiden Viscard, and an S class mage from Tartaros, Maggie Solfatara, were watching both Cynthia and Wendy, and even aided the two girls in their escape from the Council from afar. Shortly after that, an intense duel between White Eclipse and Fairy Tail ensued, 10 on 10, and it was watched by every guild in Fiore. The duel ended in a draw, but it was ultimately Fairy Tail's victory. After celebrations Wendy's birthday finally came around but that was the beginning of the end. Cynthia was kidnapped by the top members of Tataros and Silent Sanctum, and Fairy Tail almost most their lives. Luckily, Chelia and Jura arrived just in time to save them. The Council arrived shortly after to arrest Cynthia, but they soon realized that Cynthia was no longer there, and Aiden popped up on a large lacrima screen, challenging Fairy Tail to see if they could rescues Cynthia before she caused ruin to Fiore, who quickly accepted. At this time, the Council decided to unleash Cobra to kill Cynthia. At the same time, White Eclipse decided to send a small team to the location Aiden had provided, and with the assistance of Blue Pegasus, they managed to reach the location rather quickly. Cynthia's power was used for a creation dubbed the Omega Fire Cannon, whose power was able to destroy 30 miles worth of space at 20% power. The two teams of Fairy Tail and White Eclipse managed to defeat a few Tartaros and Silent Sanctum mages, and destroyed the cannon while Natsu and Wendy had to deal with Cobra, who was inches away from victory, but stopped due to Kinana convincing him not to. Only a few feet away from the room Cynthia was in, Natsu and Wendy ran into Silent Sanctum's Ace, Aloysius, who dominated he two in battle. Upon seeing Wendy hurt, Cynthia quickly lost control of herself. Natsu and Wendy were saved by Gildarts, Jura, Sidney, and Chelia. The first three stayed behind to deal with Aloysius while Natsu, Wendy, and Chelia went on to save Cynthia, only to find that her emotions had overpowered her, and she was nothing but a killing machine. Natsu and Chelia were trapped, and could only watch as Wendy and Cynthia battled it out, while Wendy tried to bring her friend back. After a mixture of fighting and talking, Cynthia regained control of herself after exclaiming she was a Fairy Tail wizard. This didn't last long as Aiden forcibly removed her lacrima, killing her in the process, but she held on long enough to bestow Wendy with the Flames of Friendship, which Wendy used to enter Dragon Force and defeat Aiden. Days later, White Eclipse, and Blue Pegasus attended the funeral Fairy Tail held for Cynthia, only to find that the girl had been brought back to life due to Chelia and Jura. While they celebrated, Silent Sanctum is revealed to be led by the grandson of White Eclipse's master, Jikan Calium, and Tataros is beginning to plot.

Season 2 (Darkness Rises): Six months have passed after Flames of Friendship, and things are relatively normal in Fiore. The only thing different is the creation of the two new guilds, Cosmic Star and Twilight Zone. In the background of these good times, Jellal and Meredy are captured by Silent Sanctum, and witnessed the rebirth of an evil Ultear, and Tartaros revives the dark guild Grimoire Heart, literally reviving Zancrow, Azuma, and Hades. They also revive Gray and Lyon's former teacher and Wizard Saint candidate, Ur. Grimoire Heart is eventually defeated thanks to the efforts of all the guilds in Fiore, and peace returns. But, once again, Jellal and Meredy are confronted by Silent Sanctum once more. They make a trade; Ultear is returned and Jellal releases Siegrain, who takes over the Magic Council. Weeks after this, the Grand Magic Games begin, and not too long after the games star Cosmic Star begins to cheat, using various techniques to ensure victory, though they didn't always work. During the Games, Ruika, the celestial mage in Tartaros, stole Aries from Lucy, although that wasn't her target. In the end, Cosmic Star seemingly won the Grand Magic Games, but when it was revealed that they cheated, they were disqualified (which led to them disbanding) and White Eclipse won. After this celebration, Tartaros made their move, destroying Lamia Scale, the Council building and kidnapped Lucy, along with a few other members from White Eclipse and Twilight Zone. The three guilds (and members from a few others) made their way to Tartaros to rescue their members, but things went askew as Aiden's new assistant, Hyde (or Dark Phantom) interfered with the most of the battles that occurred, without fear that Daityas (Tartaros' guild master and king of Hell) would deal with him. After the battle was done, the angels from heaven descended down, explaining how they were going to rid the world of darkness, which they perceived to be the legal mages. A large battle took place in Crocus, but in the end, everyone rallied together and managed to defeat the angels and their army. While celebrating, two forces plot in the shadows. Aiden and Hyde begin making plans for Cynthia, while Zeref begins to talk about the future of Fiore, and how the Black Dragon will soon make it's return...
