Fragments of a Scattered Faith: if you are stuck, then read.

WARNING: SPOILERS

After wasting a good frustrating few hours in Clîaban Rilag, I finally found what I needed to progress past the "find Eder's brother" stage in that quest.

The location is pretty obvious (especially as Eder gives you a hint as you approach it), but it's still tricky enough to find the exact spot.

So, if you are also having a hard time finding it and need help, here it is:

1) Notice the blue puddle on the ground, where the NPC is pointing the sword at:

2) Here's the item. Best have Grieving Mother in the party, as you'll need a cypher to read the item.

That's all.

3) Of course, Grieving Mother is not strictly needed, as you can simply visit a Dunryd Row cipher in Defiance Bay.

Unless of course you finished Act II before finishing this quest (as I did), in which case Defiance Bay will be in flames and everyone in Dunryd Row will be dead. Then you'll find a cypher in Twin Elms, if I'm not mistaken. That's why it's handy to have Grieving Mother in your party just to finish up the quest quicker, or else go to Caed Nua and speak to her (provided she's been recruited, of course).
