As a good and loyal citizen of the Dominion, I of course believe the truth that was declared by Emperor Jarec in 1376. The Elden rose to their rightful homes as gods and watch over the Dominion, blessing us even to this day! It is their blessing that ensure the Exiles will be slaughtered and kicked off the holy planet from which the Elden came! On a serious note: I honestly hope we don't find out what happened to them...My partial joke at the start of this post is why. If they keep it hinted at so we never know for sure, I'd be fine, but if they out right say "They got kicked to the curb by the Reapers!" I will be disappointed. The Elden have become the center of Dominion religion (at least for one playable race and the ruling NPC race), we can't find out what happened without a huge kick in the nuts to one faction. If they just keep it to hints, sprinkle it around, let the players piece it together so that the players can be certain but it's in a realm of being deniable to the characters, that's fine. Because that's meta knowledge that doesn't effect the characters. Sure some might put it together, but it wouldn't ruin the official Dominion standing on what happened.
