It's just Y'shtola theory, and herself is far from being sure.
It could be that we purified and assimilated it, or that we neutralized it with our new power up gained from reuniting with Ardbert.

If you go back see Temulun after the MSQ, she said to us "The light within you shines as brightly as before. More brightly, even."
