Those who have followed our walkthrough until now, already know that all Skyrim quests (including all main-quests) are treated independently, allowing players to gather enough information to complete the game 100%.
Since most main-quests are linked together, players should know that they cant advance to a new quest until the previous one is solved, and even if there are small exceptions (such as the last quest of the first act), it is a good idea to maintain an order that can help players during their adventures in Skyrim.
Some main-quests intersect with secondary quests that can be solved, or feature multiple objectives.
For each secondary quest, our walkthrough offers an independent guide that can be used to complete all objectives, without interfering with the games main plot.
The first main-quest of the second act is called Diplomatic Immunity.
It begins as soon as you meet Delphine in Riverwood, to complete the previous quest known as A Blade in the Dark.
