Does edér ask Eothas about his brother? From what I recall in pillars 1 we only really confirm that his brother spoke to waidwen and joined the war. 

Does edér end up following up on the new obvious lead of actually asking God? I haven't completed "he waits in fire" but I assume I'll be seeing Eothas soon enough and I'll be very disappointed if edér doesn't at least get a conversation like pelaginas with hylea in poe1
