An awesome community-driven TESO wiki @ Orcz:
The Elder Scrolls Online Wiki
Extremely detailed, everything there written by adventurers just like you
If you have any info to add like details about NPCs, locations, quests, etc, feel free to contribute so that we can build a great source of knowledge about the game
Cheers
