Where is the 7th daughter of chaos?
We know there are 7 daughters of chaos, as seen in the opening cinematic, with Quelaag, the Fair Lady (Quelaan in the game files according to another redditer), Quelana, and the one unnamed (or called Grana, the eldest daughter, according to the "Souls Lore" wikidot) outside the Izalith boss room being the only confirmed ones we see.
Then there's the, I guess, theory that the two trees/weakspots on each side of the Izalith boss are the 5th and 6th daughters, but what about the 7th? I've seen someone say that she's the one buried in the Ceaseless Discharge boss room where we get the Gold-Hemmed Black set but the description says they belong to Quelana so the 7th daughter can't be there right?
So where could she be? Is there any indication, description, dialog or anything that points as to where she might be, or could have gone? Did she just die when the Flame of Chaos went out of control, or is she somehow the Lost Sinner in DS2, which is the only other theory I've heard.
I haven't seen any more theories about this, like at all, which i find odd...
