The first Skyrim act starts after the introductory cutscene, during the dragons attack over the city of Helgen.
This act includes seven main quests.
It is important to know that in Skyrim; the main quests are linked, meaning that in order to unlock a new main-quest, you have to complete the previous one.
Since our Skyrim walkthrough, tries to cover the full game, you should know, that all quests (including side-quests) are treated independently, in order to offer enough information so you can complete them faster.
Additionally, for each quest, we offer information on the enemies you will encounter, the rewards you receive and the locations you have to visit.
After you create your character, watch the cutscene, and get ready to start the first quest in the game: Unbound.
