The War of SandWing Succession, also known as The Great War, was a war over the heir to the SandWing throne. Five of the Pyrrhian tribes were involved, excluding the RainWings and NightWings. The event began nearly twenty years before The Dragonet Prophecy in 4,992 AS.
Twenty years ago, Queen Oasis was killed by Stone, a scavenger, in an attempt to steal the SandWing treasure with Heath and Rose. Among the stolen treasure was the Eye of Onyx, which was used to choose the next SandWing queen. Blister allied with the SeaWings, Burn allied with the SkyWings and MudWings, and Blaze had most of the SandWings supporting her, and also allied with the IceWings. The war ended with Sunny finding the Eye of Onyx and giving it to Thorn, who became the new SandWing queen.
- Heath, Rose, and Stone broke into the palace to steal the SandWing treasure. Oasis goes after them and was killed by Stone in the process.
- Burn tracked down the scavengers and burnt down their dens. Blister stole some of the treasure for herself during Burn's absence. Councils are held on who should be the next SandWing queen.
- Rose is found and adopted by Smolder.
- Blister allies with the SeaWings and MudWings. Burn later forms an alliance with the SkyWings and attempts to contact the IceWings, but they are already allied with Blaze, who also has the majority of the SandWings on her side, and the war officially begins.
- Morrowseer and Battlewinner create the Dragonet Prophecy, which is part of the NightWings' plan to take over the rainforest. Blister forms a secret alliance with the NightWings and gains favor with the Talons of Peace.
- Commander Tempest of the SeaWings is assassinated by Deathbringer, resulting in the MudWings splitting off their alliance with Blister. Burn threatens the MudWings to force them to ally with her.
- The Talons of Peace gather the prophecy dragonets' eggs. Hvitur and the SkyWing egg are killed by Burn and the latter of which is replaced with Glory's egg. Asha is caught in the crossfire between Blister and Blaze's forces and dies of her wounds after delivering Clay's egg. Webs steals Tsunami's egg and Dune steals Sunny's egg. Morrowseer brings Starflight's egg to the Talons of Peace.
- All SkyWing eggs that were going to hatch on the brightest night were killed under Queen Scarlet's orders so that the prophecy would not be fulfilled. According to the guards, the eighth egg escaped somehow.
- The brightest night occurs, and the dragonets hatch.
- Six years later, the dragonets of destiny attempt to escape from their cave in the Claws of the Clouds Mountains. They are taken prisoner by Queen Scarlet, along with Kestrel.
- Queen Scarlet invites Burn to her palace for her hatching day to see the dragonets and to give Sunny to Burn as a gift. The dragonets soon escape after Glory sprays Scarlet with her venom, nearly killing the SkyWing queen.
- Around the same time that the dragonets escape from the Sky Kingdom, Blaze's army attacks the MudWings. The only named loss of this battle was Crane, one of Clay's sisters.
- Burn's alliance bombs the Summer Palace during the dragonets' stay due to the work of Crocodile, a Talons of Peace infiltrator. The SeaWings flee to the Deep Palace, breaking their alliance with Blister.
- Nautilus, then the leader of the Talons of Peace, and Morrowseer come up with a set of replacement dragonets of destiny, known as the false dragonets.
- The MudWings and SkyWings plan to attack the IceWings, the idea being to "kill them all, take no prisoners." They decide not to after Sunny dreamvisits Queen Moorhen and manages to talk her out of the idea.
- On the false brightest night, Sunny has the heirs and most of the tribes meet up at Burn's stronghold. Sunny plans for the sisters to peacefully choose who the next queen is or have the SandWing tribe decide.
- Blister gifts Burn a dragonbite viper, which Burn pins in her talons. A second dragonbite viper leaps out of the box and kills Burn. Blister attacks Blaze after Burn's death.
- Rose helps Sunny find the Eye of Onyx and Sunny gives it to Thorn. Blister attempts to steal the Eye for herself but is electrocuted and incinerated due to the Eye's enchantment. The Eye of Onyx chooses Thorn as the new SandWing queen.
- The queens sign a peace treaty and accept Thorn as the new SandWing queen, ending the war.
