[Chapter] 74 [Entry] 
She once asked Ruin why he had chosen her. The primary answer is simple. It had little to do with her personality, attitudes, or even skill with Allomancy. She was simply the only child Ruin could find who was in a position to gain the right Hemalurgic spike—one that would grant her heightened power with bronze, which would then let her sense the location of the Well of Ascension. She had an insane mother, a sister who was a Seeker, and was—herself—Mistborn. That was precisely the combination Ruin needed. There were other reasons, of course. But even Ruin didn't know them.
