Fragments of a Scattered Faith

 is a side quest and companion quest for Edér in.

Overview
Eder's a veteran of the Saint's War, who fought for Dyrwood against St. Waidwen. He is convinced he and his brother fought on the same side, but rumors that circulate, rumors that say Woden fought for the opposing side, are making him question that conviction. Woden always knew which side to take and Eder acted accordingly, following his brother's lead.

So what if Eder was wrong about who his brother fought for?

Walkthrough

 * Acquire Edér as a companion in Gilded Vale. This can be done after speaking with Caldara de Berranzi during Visions and Whispers.
 * Bring him along for the conversation with Maerwald.
 * After talking to Maerwald, Edér will explain his doubts about his brother's intentions during the Saint's War. He decides the next logical place to look is the records department in Defiance Bay.
 * Speak to the Records Keeper in the Ducal Palace in First Fires. If you have at least Friend (Somewhat Good) reputation in Defiance Bay he will give you access to the military records you need. Intimidating him with a Might 16 check will not cause him to yield the records, but also won't prevent you from getting them later when you have the requisite reputation.
 * If you have at least 17 Perception, you will notice that the Records Keeper's accent is not native to Dyrwood, and he is likely from Readceras. This opens a Resolve 17 option to bypass the reputation requirement. At 19 perception, you also notice imprints of shackles on him; this opens a Lore 5 option.
 * Travel to Clîaban Rilag. On the river in the east is a small camp at which you have to loot the Readceran standard piece.
 * Have a cipher analyze the standard piece. This can be done by the player themselves if they're a cipher; by Lady Webb or Kurren in Hadret House; or by Grieving Mother. Alternatively, if you are without Grieving Mother and have progressed past Defiance Bay, you can have a Fangs Mind Hunter in Oldsong (located by the water and jetties on the Western side of the map) de-cipher it for you.
 * If you have recruited Grieving Mother, but she was not present when you pick up the piece, you can still speak to her about it out of party in Brighthollow at Caed Nua.

Post quest dialog
Once the quest is completed and you've rested once, Edér will have additional dialog. Your choice during this dialog can affect Edér's ending.
