Serana, it comes to play, is a very important part of the puzzle to find an Elder Scroll - the main quest - and to thwart the Tyranny of Sun prophecy that will wipe the vampires out. Skeletons and ghosts and ethereal balls of light roam around, and lightning strikes around us. It's an eerie, otherworldly place that's almost black and white. The quest we activate and follow with her has us summon stony steps to a place called Soul Cairn. We're in a tomb with a woman called Serana, who's either a vampire or had a very late night, judging by her red eyes. In our E3 demo, we're already hours into the Dawnguard expansion, and we're a level 29 Vampire Lord. The content will be available early on in the Skyrim game, but the real meat won't begin until level 10. Hours in, you'll face a choice - do you want to be a Vampire Lord or do you want to join the Dawnguard, the vampire hunters? You'll hear about the new content through Skyrim's guards, who tell you the Dawnguard are recruiting. In Dawnguard, you can become a Vampire Lord.
