I'm positive that Marasiah's mother and Hogrum Chalk are intended to be descendents of Allana. Just as Roan Fel is basically confirmed to be descended from Jaina and Jag by this point. Which come to think of it...means that Marasiah Fel is the first product of incest in the EU? Beccatoria, thank you for making me feel not alone. My biggest complaint about the EC is that the changes made really alter the flow of the ending scenes, for the worse. (I do like the backstory from Leviathan, even if playing it ahead of one's first playthrough kind of takes a lot of the wind out of the ending.) Also, on this tangent, I think Karpyshyn's original ME3 ending idea is completely nonsensical.
