I see there's a little confusion regarding what drops these, so I'll clear it up by posting this on the forums for all three recollections.
All three appear in all promyvions, but they're dropped by different mobs in each promyvion.
In Promyvion-Dem:
Wanderers drop Recollection of Pain
Weepers drop Recollection of Guilt
Seethers drop Recollection of Fear
In Promyvion-Holla:
Wanderers drop Recollection of Fear
Weepers drop Recollection of Pain
Seethers drop Recollection of Guilt
In Promyvion-Mea:
Wanderers drop Recollection of Guilt
Weepers drop Recollection of Fear
Seethers drop Recollection of Pain
This should clear everything up. :)
