Just post your expansion Idea With a little Story behind it.
No "I want to ride dragons" Or " Spell Making"

Example: Curse Of The Dilon Lir DLC idea
The Dragonborn (Player) is lead into an ancient cave by a mysterious stranger from an old guild for a cursed stone (the player is unaware of this at the time). Throughout the cave the Player will encounter common enemies(Frost spiders, draugr, ect) and traps. The Stranger (NPC) will retreive the stone and a draugr boss appears. The player and Stranger will escape the cave then part ways. The player will receive a note from a messenger asking them to report to Whiterun. When they get to the city they will notice barricades set up at the entrances with Soldiers(Imperial,Stormclock,Neutral Depending on player's choices). The player will meet the commanding officer and will be told of the events of a Infection going around turning citizens into Draugr. The player will be set on a questline to find and destroy the stone to break the curse. 2 cities will be infected at a time. The player can clear the city out for citizens to come back and resume normal. Cities can become infected again. Its random. If you finish the questline while a city is infected the city will turn back to normal. Any ideas to add to this just let me know.

PS: this is a real Idea
