Uncover the secret of Gazarath. (Various notes and books found around the world can help The Warden complete quests or give clues to hidden treasure.)
These codex entries are (with one accidental exception) related to quests that can be completed by the Warden. In some cases, the codex entry can be found before the quest appears on the "Current Quests" tab of the journal and a further event, or update to the codex entry, must occur before the quest can be started.
Note that numbering of quest-related codex entries will depend on the DLC installed. The initial numbers given here are those when only the original campaign is installed, along with modifiers to numbers when The Stone Prisoner and Warden's Keep and Return to Ostagar and Feast Day Gifts are installed.
