Ok I didn't want to be done with Dragon Age yet so I read all of the Dark Horse comics and like are those canon? Because if so then (SPOILER)Morrigan's son has an old god soul, possibly the blight taint, Flemeth's genes, and dragon blood if Alistair did the ritual. Even if it is canon I don't expect they'll do much with that but can you imagine all the sparklypoo mary sue fanfics that must be floating around out there?

Also fun fact: I didn't realize until I was on the final boss that you could revive party members.
