Legend in the Sky (Sky Castle), creates a new player home in the sky. In order to obtain this house you will need to complete a quest. The quest begins after you purchase (or steal) "Sky Castle" from the First Edition. Sky Castle contains a riddle that details locations which will then lead you to the actual Castle. At the end of the quest you will recieve a new armor along with the castle.
A mysterious tome falls into the hands of the owner of the First Edition, a book filled with cryptic riddles. Coupled with the rumors of floating castles in the sky, something seems to be trying to break into the realm of Tamriel.
Complete the quest to gain access to the castle, its armor and NPCs. And a spell that summons a portal bringing you to the main chamber.
