you are the dragonborn, the hero of skyrim. You are currently in a dwarven ruin, doing your normal treasure hunting and Dungeon clearing. At the end of the ruin, you find a weird device that you pick up to investigate. You find a button on it and press it out of curiosity before blacking out.

you wake up to the sounds of nature and birds singing. You get up and look around to see you're in a small forest. It doesn't look anything like skyrim however, things look more... bright and colourful.

you get up as your headache fades away. You walk out of the little forest to see a big castle in the distance, a section of it looks like it's being held up into the air. Now the rest of your journey... is up to you.
