The first DLC for Skyrim is titled ‘Dawnguard’. The story centers on a vampire lord who is looking to blot out the sun. There will be several paths to the story where you can either become a vampire yourself and help him out.. or join with the Dawnguard and put a stop to his plans.
Rumors are also circulating that there will be tougher dragons to do battle with. Along with death trolls, gargoyles and armored hounds. Along with all of that are of course tons of side quests, new weapons such as crossbows, new armor sets and a new set of perk trees for werewolves and vampires. Also, there will be a new shout called Soul Tear, which steals the soul of an enemy, chaining them to your command.
