Fully Flying Dragons
If you're willing to put up with bugs take a look at this incredibly cool mod that allows you to summon and ride various types of dragons.
Fully Flying Dragons, in its current state, allows you to summon 58 different kinds of dragons to ride around Skyrim.
The list includes Black, Purple, Snow, Tyrant, Skeletal, Paarthurnax, Wingless, Boss, Defective Lich, Ice Lake, Durnehviir, Flying Chaurus, Alduin, Odahviing, Forest, Tundra, Flesh, Fat, Great Wispmother, Evil, Crystal, Red, and more.
Once you acquire the tome you can summon your flying mount using simple controls to fly around Skyrim Special Edition's world.
Again, the mod isn't perfect but we expect the developer to release updates in the weeks ahead. It's only available for the Xbox One.
