Without sounding to horrible, that is a really silly comment. You slayed the arch demon and your companions just left your body lying cold on the floor whilst they went for lunch?? Sorry but once you decline the ritual, Morrigan has no way of getting close, and NO she couldnt finish the ritual in some bird form, that is getting silly and if the lore did take that pathetic route, I am stating now I will not support it.
If you decline the ritual, Morrigan doesnt have a god child - simple really. There is really no convincing argument to make me think otherwise atm. Otherwise there would not have been the Orlais and not pregnant epilogue in the game.
Rather close minded approach don't you think?
The reality is no one has ever attempted a ritual such as this before according to the lore, at least it's never been mentioned. There are no step by step instructions given, no guideline or list of requirements laid out. All we know from our end is she needs to be impregnated by a Grey Warden, if we refuse on our end and Alistair's Riordan is a legit possibility. A beautiful young woman asking to bed with him, a little magic if he needs some further encouragement. As for the death, hell maybe saving the Grey Warden was simply an option she could exercise. You refused to help her so why should she help you. The whole ritual is just so vague I'm not sure how you can say there is no way it could work. I spoke of a possibility, rather silly I admit, not anything derived from facts because there are so few facts to actually go off of.
As for the epilogue, the furthest it goes is speaking of a woman fitting the description. Never directly says it's her. Breathing room, gives them the ability to go in any direction they want much like Leliana's epilogue if you romanced her and died. Nothing conclusive, just hints and speculation which allows them to take things wherever they want without backtracking and stepping on their own feet. Most other epilogues are rather conclusive, it's interesting the ones which would possibly pertain to a continuation of this story are left wide open to interpretation.
Actually its said quite clearly its the soul.
I'm curious, where did it mention that the essence=soul, I was fairly pretty anal about the Codex's and never remember reading or hearing it? Does a God indeed have a soul?
