My first idea is for you to be able to take over Skyrim. The Dragonborn would easily be able to rally soldiers to try and make him high king of Skyrim. Or maybe you don't want an army just a horde of mindless zombies or bandits to take villages with. The choice is up to the player. Maybe even some cool magical siege weapons too?
My second idea is more for the magic users of Skyrim. At the college of winterhold A student has been banished, simply due to researching a certain kind of magic (if you are in charge of the colleague the student is brought before you for you to decide his fate). He tells you about a mythical island containing magic beyond possibility. Eventually you travel to this land to discover a hooded man, you cannot see any part of him except robes. He talks about how the island has what you seek but for a grave cost, you can now choose to go back or not. If you continue he will take you inside a ruin. There he reveals what he truly is. What's left of a high, now tainted by magic and a soul gem in a fancy chest plate, placed over his heart. He is a slight blue with weird pattens. He says how if you become one of him you unlock new magic.
Becoming one of him brings new spells like summoning tornadoes, lifting people off the grown and taking over people but ta the cost of turning into one of him
Please give me your response and if there are any skyrim makers out there tell me if it gets in the game or not
