Integration: The Stranded Light includes more than 80 quests with a strong emphasis on thinking, character interaction, choices, consequences, and lore. It delivers a seamless integration of Cyrodiil and Shivering Isles along with other lore races. A new, joinable guild plays an important role in many of the quests, which are unlike any in Vanilla Oblivion: A bit thinking, often multiple solutions, quite heavy on social skills. It also reaches beyond the typical mold of quest mods, seeking to enrich the existing game world as whole. The quests in Integration: The Stranded Light don't all follow a single storyline. It's more like a collection of somewhat intertwined short stories than an epic novel.
Integration adds several new guilds that you may join. Each with their own quest lines and rankings, Stranded Light being the main Guild and at least vaguely connected to the other guilds.
Note: Missing from this GIF is the newest guild added 12-31-09: "The Disciples of the Moment" ; an artistic guild on the Shivering Isles.
