World of Warcraft: Dragonflight will be a deeper dive into draconic lore than any previous content in WoW. Feasel teased several mysteries that may be uncovered during the story, including the origin of the Emerald Dream and the nature of the timeways of the bronze dragonflight. He also hinted that, in addition to learning about the origin of the new playable drakthyr race, players could expect to learn more about other draconic creatures, like dragonspawn and drakonids.More lore for other Dragonkin.The draconic politics will extend beyond just the five dragonflights and the Primalists, however. Feasel made mention of the other types of dragons players have encountered over the years, such as the twilight dragonflight, the stone drakes of Deepholm, and the storm drakes of the Broken Isles, and that some of these groups may hold resentment over not being included in the main dragonflights. Players should expect these flights–and perhaps others, like the netherwing dragonflight from Burning Crusade — to be involved in the drama of the Dragon Isles as well.
Lots of dragon politics including older broods like the Netherwing.
Origins of the ED, explains why Tyrande's supposedly involved again.
Maybe (hopefully) they'll finally let Freya do something this time.
