Well, a great plot idea could be that the male with wings is a messenger from the gods. He has to deliver important prophecies to the different holds in Skyrim. However, many of the Jarls don't believe him at first because of his strange appearance. His wings also make him a target for bandits who want to capture him and sell him to some sort of dark magic user. As he travels, he meets a group of adventurers who help him on his mission.
Maybe the male with wings is part of an experiment gone wrong by a mad wizard. He escapes the wizard's lair and now tries to blend into Skyrim society. But his wings keep getting in the way. He could start off as a loner, but as he gets involved in local events, like helping a village deal with a plague of giant spiders, he gradually earns the respect and friendship of the people. His wings end up being an advantage as he can scout from above and warn of approaching threats.
One idea could be that the male vampire dragonborn struggles with his dual nature. He has the power of the dragonborn but also the thirst for blood as a vampire. For example, he might face a moral dilemma when using his dragon shouts to save a village that is afraid of his vampiric side. Another plot could involve him seeking a cure for his vampirism while still trying to fulfill his destiny as the dragonborn. He could travel to ancient ruins in search of a lost spell or artifact that might reverse his condition.
Perhaps the male Dragonborn is cursed by an enemy, and Nocturnal offers to break the curse in exchange for his loyalty. This loyalty then develops into a deeper connection as they face challenges together, with Nocturnal guiding the Dragonborn through the more mysterious and shadowy aspects of Skyrim's lore.
A possible plot idea is that they are both chosen for a special mission by the gods. This mission forces them to rely on each other in ways they haven't before. As they travel to different parts of Skyrim, they encounter various cultures and traditions. Sharing these new experiences brings them closer. Also, the Dovahkiin could be struggling with his dragon blood, and Aela helps him come to terms with it, leading to a romantic connection.
A cool plot could be that a powerful artifact in Skyrim is causing chaos and the Fairy Tail members are summoned to find and secure it. Along the way, they meet up with the Dragonborn. Some members might befriend the Dragonborn and help in their battles, while others might be a bit more skeptical and think the Dragonborn is a threat to their own power within the group.
One idea could be that Percy Jackson finds himself magically transported to Skyrim. He could use his water - bending abilities in the frozen landscapes, perhaps to help deal with frost trolls by using water to freeze their legs or something. Another plot could involve Annabeth Chase coming to Skyrim and using her strategic mind to navigate the political intrigues of the different holds. And maybe a demigod from PJO teams up with a Dragonborn in Skyrim to fight a common enemy like an ancient evil that threatens both their worlds.
One idea could be that the Master Chief is somehow transported to Skyrim. He might use his advanced combat skills and technology to deal with the dragons. For example, his energy shields could protect him from dragon fire. Another plot could involve the races in Skyrim getting access to Halo's weaponry and having to figure out how to use it. Maybe the Dwemer could reverse - engineer Covenant weapons.
Well, perhaps Eragon's dragon, Saphira, is injured and they have to seek out the healing magic in Skyrim. Along the way, they meet the Dragonborn. The two dragon - related characters could either become friends or rivals. Eragon might be amazed at the variety of dragons in Skyrim, some of which are different from the ones he knows. And he could share his knowledge of dragon - riding with the Dragonborn.
One idea could be that the Dragonborn is somehow transported to the RWBY world. They could use their shouts to combat the Grimm. For example, 'Fus Ro Dah' could send Grimm flying back, and the local Huntsmen and Huntresses are both amazed and a bit wary of this new power.
One idea could be a Hobbit finding their way into Skyrim. Maybe they get mistaken for a child at first due to their small stature. They could bring their Hobbit - like skills of stealth and a love for food. For example, they might start a small cooking business in one of Skyrim's towns, using unique Hobbit recipes and ingredients they manage to find in Skyrim. This could attract all kinds of characters, from the local Nords to the wandering adventurers.
